I've been having this problem for almost a week now where the Market Place and the Dressing Room applications do not work and fail to load. The Market Place specifically says that I'm playing in an "Invalid Session" and suggests restarting the game, which doesn't change anything, and the dressing room is stuck in an infinite loading loop for skins, the customization buttons are bricked and do nothing, and all of the skins are greyed out forcing you to play with a default skin even if you've paid for content. I was able to access these features 1 time on my phone this week, but they do not work on the Windows 10 Bedrock Application.
