Multiplayer automatically turns off after entering any world on Android

Short description:

On Android Bedrock Edition, the "Multiplayer Game" option automatically turns off and becomes greyed out after entering any world.

Steps to reproduce:

1. Open Minecraft Bedrock Edition on Android.

2. Create a new world.

3. Enable "Multiplayer Game".

4. Enter the world.

5. Open the world settings.

Expected result:

The "Multiplayer Game" option should stay enabled, and other players should be able to join my world.

Actual result:

After entering the world, the "Multiplayer Game" option automatically becomes disabled and greyed out. No one can see or join my world, and invitations are not received.

Additional information:

I tested this with different Microsoft accounts, different worlds, and another Android device. The issue also occurred in the Beta version.
