For diver continuous months and even after the nether update, I still cannot access marketplace content or my skins. I cannot purchase anything on the marketplace or even make new skins

I've tried deleting so many different worlds, clearing local storage on my Xbox, restarting it, un-installing MC, clearing MAC address, even buying a new WiFi modem and checking network status (my network status is fine), so many different things in an attempt to get the marketplace working but the marketplace is still horrendously broken for a very long time for me. I also see that I only have this issue so far.... please help.
