[Android 11] People wishing to restore a migrate backup zip on Android 11, kindly try this workaround and provide feedback if it is working for you. 1. Don't click on the helper notification. Go to Developer options. (Settings -> About phone -> tap Build number 7 times. Then go back to main menu in settings -> System -> Advanced -> Developer options) 2. Disable the option "Verify apps over USB" 3. Now you open the helper and and restore should work fine for all apps.
Kindly let me know if this works for you. This toggle will be done automatically on the next version.
