Achievements on Windows phone won't unlocking

Me and others are having problem with unlocking achievements on Windows 10 phone. Minecraft on Windows phones are working fine, can playing online with other players and join servers no problem. But achievements seem have stopped working. When I went on my profile, click on "Achievements" button, it says "Fetching Achievements..." on the black screen and it stays like this forever! Nothing happen. It has been like this since 4th November 2020.

I only need few more achievements to get 100% but it not working anymore and I'm hoping you guys can fix it?
