I Had the same problem and tried to solve it for a view month now, every now and then. Its not essential for my app but a nice feature to have. So, the solution for this problem is the same as for the notification problem. Notifications for Android did not work as well, but i fixed it within a day.
If things work fine for you on development build and the features you’d like to use would definitely work with ARM64, then use a custom Proguard, activate it as shown in the image above on Project Settings/Player/Publishing Settings.
Then move to the Proguard file (image below), open it and type in -keep class com.starseed.** { *; }.
You might also mention this package in the manifest. Try this with all features that should work, but somehow don’t.
