Can't Access servers, marketplace and achievements after signing in

Dear mojang,
I am a pocket edition user.I like to play minecraft.A bug that makes this game irritating is that after signing in to the microsoft, the game works normally like you have servers available and you can buy and download texture packs,worlds, emotes but after quitting the game the game probably don't save the changes i made. The game acts like i have no network available even after the network speed is normal and now i can't even use servers it shows coming soon and the game shows that there is no emotes even after i equipped these emotes earlier. And the game deactivates all texture packs even after i activated these texture packs earlier.And finally the game replaces the skin i had earlier to the random skins i had long time ago and the 1.16.200.51 beta menu screen that was in black and white colour will be replaced in to the normally coloured screen for 1.16.200.51 beta after the bug comes into play.I can fix this bug by uninstalling and reinstalling the game,but after quitting the game the bug will return again. I can't do anything about this because i have to uninstall and reinstall again and again to just play and enjoy this game properly so please i am begging you that fix this bug.Also i can't even view my achievements because of this annoying bug, again i am begging you that fix this bug.
