I have a different version for the v3 as I also beta test. I am on 126.96.36.199. I am also on Android 12 Pixel 5 and a Pixel 6. Both work without issues.
You cleared the App Cache, but did you do this in the app itself under Account, App Settiings? You should clear the Cache in bot area’s, in the App as I mentioned and the through the OS by Long Pressing the app, doing a force stop and the go to Storage and Cache and clear Cache.
the other option I would do is to log out of the app, restart the phone. Then when you start the app and logon everything should be cleared out. Just trying to provide options. What I have mentioned above helped me out in the past.
You can always going the Beta Program, understanding that at times there could be some issues. If you want to try you can go here: Become a Beta Tester, after you join, remove the app then go to the app store and install it again. Then in the Account, About menu choice, you will see Beta Program. Click on that, then select Edit in the top right and select the Devices you would like to Beta Test the FW for. Click save and then go to Firmware Update and see if the Beta is available to you.
