Need a C# programmer to create a ZennoDroid cube with correct save/restore of application data.

Task Description:
There is a project in ZennoDroid that works with the MEMU emulator (Android 9.0) with an Android application (the name will be provided in private messages).
After the default cube saves the application data and then reopens it, the account within the application automatically logs out. Upon launch, a system notification appears in the spirit of "Don't forget to back up on the old device", after which the "restored" account goes into logout and requires new authorization. The same applies to saving the original emulator entirely (.ova). Upon subsequent opening - logout.

Goal:
It is necessary to understand why the authorization state is not preserved upon restart and to implement a cube in C# that:

1. Correctly saves all application data (including authorization, cache, configs, and databases) between sessions.

2. Allows running the same application on the same or another emulator without losing authorization.

3. Works stably in the multithreaded mode of ZennoDroid.

Requirements for the Developer:

• Experience with C# in ZennoPoster / ZennoDroid.

• Understanding of Android data structure (/data/data/, shared_prefs, databases, app_webview).

• Ability to work with ADB, root permissions, and data copying/restoration scripts.

• Ability to localize why auto-logout occurs after restoration.

Expected Result:

• Upon restarting the application, the account remains authorized, and the "backup" notification no longer appears.

• The cube fully automates the process of saving and restoring the necessary files/folders.

Payment:
By agreement after successful testing of the solution on several emulators.
