I have had this same issue for about a month now and it was pretty angering and made the game not worth even playing. I did find a fix for me however and I hope it can help one of you guys out. I downloaded the xbox app and had to be signed into the proper xbox account that I was using with msfs. But I initially had a problem where it would not let me sign in and the box would just be grey and disappear. I then got it fixed using a YouTube video and signed in properly. The video is titled, " Fix Sign In Window Flashing | Xbox App | Windows Guide." No, this is not to promote any youtuber or anything. The video basically says to go to task manager->serices->open services->find all xbox titled services->go to their properties-> make them automatic. If this doesn’t work, make sure that the xbox live service is updated for those in ms store, as it was not updated for me. I hope this works for you guys!
