Realms missing + Dressing Room bug + Xbox account not working + Old UI showing (Android 1.21.81.2)

Device: Samsung Galaxy A20

Minecraft version: 1.21.81.2

Android version: 11

Summary of the issue:

After updating to version 1.21.81.2 of Minecraft Bedrock on Android, the game became nearly unplayable due to multiple bugs:

- The Realms tab does not appear

- When trying to equip a cape in the Dressing Room, it loads the Marketplace screen instead

- My Xbox account is connected, but I can't play — neither multiplayer nor offline

- The new user interface (UI) does NOT show — I'm still seeing the old UI

- I tried clearing cache and app data, but nothing fixed the issues

Please fix these bugs. The game has become unplayable since this update.
