Android 11 Save Game not working

Use of " ExternalFilesDir" can delete save game on updating the game. So this is not right solution. Now what would be the best solution to save game on android 11?
Save game working fine on android 10 but because of scoped storage used in android 11, Games developed with UE4.26 not saving game in Android 11
Kindly give me solution

I have the same problem. Even ExternalFilesDir not working.
From adb logcat:

ue4 java.lang.IllegalArgumentException: Primary directory UE4Game not allowed for content

Clearly a permission issue. The save files doesn’t get created.

Have you tried it on 4.27?

I’m on 4.27, fresh install, doesn’t work.
