While our DC on Mobile(v2) mobile app contains many new features and enhancements, it does not yet support all of the features available in the VAS Platform(v1) mobile app. We are also updating PULSE to support DC on Mobile(v2). As a result, some PULSE feature updates may not be applicable to or supported by VAS Platform(v1). To take advantage of these new features, VAS recommends upgrading to DC on Mobile, which you can download from the app store on your mobile device. For more information about the mobile apps VAS currently offers, see [Mobile Apps](docId\:LrbWjLC6pBiEQt-JRs1XB).

Known issues and workarounds for the DC on Mobile(v2) mobile app include:

-  Known Issue  The following known issues related to the new [copy event data from the last animal](docId:4ovpwQlaPjqpvXJirQQ5Q) enhancement exist in this version of the app:
  - When copying event data to additional animals, unchecking a copy data box, and saving changes, the unchecked copy data box may remain checked. This is cosmetic only, as the unchecked data will actually not be copied to the next animal if you continue.
  - When copying protocol A dairy protocols include a series of treatments or tasks that follow a prescribed order and schedule. Protocols may be defined for reproduction purposes, to treat an illness, or for routine vaccinations. event data to additional animals and deleting an animal from the event, the copy icon

at the top right of the Events screen may remain enabled unexpectedly.

-  Known Issue  If you tap animals in grid mode too quickly, the next animal selected may not open. Wait until the previously selected animal closes before selecting the next animal.
-  Known Issue  If your iOS device is on operating system version 26.0, you may see a "No permission granted" message when connecting a scanner (even if you have allowed the app to use Bluetooth). You can disregard this message. Devices on other iOS versions are not affected. See [Troubleshoot Scanner Connections](docId\:Tw99jpd0HW37hkRJTXFAw) for help connecting your scanner.
-  Known Issue  When selecting to **Undo** a task on ToDo worklist, the task closes rather than leaving it open with the option to Mark as Done.
-  Known Issue  The Bluetooth Low Energy (BLE) connection is not supported on RFID scanners in this release. Connect your devices with Bluetooth Classic until we are able to resolve this issue, but please note that iOS devices only support BLE connections on some scanners. See [Tips for Using Bluetooth Low Energy (BLE)](docId\:Tw99jpd0HW37hkRJTXFAw) to learn more.
-  Known Issue  You may notice slower RFID scanning speeds in this release, which we're working to resolve as soon as possible.
-  Known Issue  Events with incomplete information may be sent to Platform when you tap `Process All Changes` at the top of a worklist A worklist is a structured list of tasks or animals requiring attention, typically used to organize and prioritize work. In PULSE and the mobile app, worklists identify animals that need to be seen by dairy workers or animal health experts for specific reasons, such as pregnancy checks or treatment in a hospital pen.. VAS is working to resolve this issue in a future release, but we recommend always completing all required information when entering events.
- Workaround If you enter an event on a vet list, undo it, and then attempt to add another event, the vet list changes cannot be processed and sent to PULSE. To avoid this issue, use one of the following workarounds:
  - Use the Events screen to enter the events in the DC on Mobile(v2) app. See [Events](docId\:e-WCEtRy4dtmIOd-iy-k4) to learn how.
  - Manually add the event directly in PULSE. See [Enter Events (v2)](docId\:Jr32JQW0P20BCKOGdcXMJ) to learn how.
  - Use the VAS Platform(v1) mobile app to enter vet list events until a hotfix is released for the DC on Mobile(v2) app. See [Create a New Event or Edit an Existing One](docId\:F_A926cld2BC2GGALDb63) to learn how.
- Workaround In [Events](docId\:Jr32JQW0P20BCKOGdcXMJ) or [Tasks](docId\:ZfB8oC9gL-tkl0stlx9RO), the RFID** Scanner** toggle may be on when your RFID scanner is **not** actually connected. Close and reopen the app, and then reconnect to the RFID scanner to resolve the issue. See [Connect Your RFID Scanner](docId:3ilmu87JFbbNxSyt1___U) to learn how.
-  Known Issue  When you open a newly added worklist A worklist is a structured list of tasks or animals requiring attention, typically used to organize and prioritize work. In PULSE and the mobile app, worklists identify animals that need to be seen by dairy workers or animal health experts for specific reasons, such as pregnancy checks or treatment in a hospital pen. for the first time, the app might crash. The app will not crash the next time you open the worklist A worklist is a structured list of tasks or animals requiring attention, typically used to organize and prioritize work. In PULSE and the mobile app, worklists identify animals that need to be seen by dairy workers or animal health experts for specific reasons, such as pregnancy checks or treatment in a hospital pen..
-  Known Issue `MyDC ONLY` When you process Open Tasks in Online Mode, the app indicates how many animals need to be processed. However, when you process Open Tasks in Offline Mode, the indicator may not be displayed even if animals need to be processed.
- Workaround If you work with multiple users and/or dairies on the same device, the app may show data for the previously viewed user or dairy. As a general rule, VAS recommends always refreshing herd data after switching to a different user or dairy. See [Refresh Herd Data in Online Mode](docId:3ilmu87JFbbNxSyt1___U) to learn how.
- Workaround If you turn on **Airplane Mode** on your iOS device, Bluetooth is turned off automatically. You can turn Bluetooth back on in settings, and it will stay on until you turn it off or toggle Airplane Mode off and on again.
- Workaround If you complete a pen correction for an animal, the app updates today's open worklist A worklist is a structured list of tasks or animals requiring attention, typically used to organize and prioritize work. In PULSE and the mobile app, worklists identify animals that need to be seen by dairy workers or animal health experts for specific reasons, such as pregnancy checks or treatment in a hospital pen.s and changes the pen information for the animal to the corrected pen.
