Windows Phone 7, 8 and 8.1 Achievements Not Syncing to Xbox Live Profiles since March 2020

Since March 2020, achievements that are unlocked on windows phone 7, 8 or 8.1 will not sync to Xbox profiles. I've seen numerous people reporting that they have the same issue. That being when you unlock an achievement on windows phone 7, 8 or 8.1 it will
unlock however won't sync to your profile. This issue also happened in October of 2019, however was resolved and achievements started syncing again throughout November 2019 - February 2020. It is now broken again and needs to be fixed.

For me I'm using a Lumia 640 running Windows 8.1 and the achievements I've earned in March and May 2020 haven't synced. Everyone has the exact same problem and it is occurring on all windows phones using 7, 8 and 8.1 os.

This a service issue, I hope it gets fixed.
