It seems that the View button on your Xbox controller is not working properly when connected to AMD Link on your iPad Pro or iPhone 13. Since the button works fine when connected to your PC, it may be an issue with the AMD Link software or the connection between your controller and the iPad/iPhone.
You can try a few troubleshooting steps to see if it helps. Firstly, try restarting both the AMD Link software on your iPad/iPhone and your Xbox controller. If that doesn't work, try resetting the controller by holding the pairing button on the back for 10 seconds until the Xbox button starts flashing.
If the issue still persists, you may need to check for any updates for the AMD Link software and your iPad/iPhone. Also, make sure that your controller is compatible with the device you are using it with and that it has the latest firmware update installed.
If none of these steps work, you can try reaching out to AMD support or the Xbox support team for further assistance.
