On minecraft.net the login banner is not showing up, also when I go to https://www.minecraft.net/en-us/profile/ it just loads forever. I have tested on multiple browsers and pc's and 2 networks.
This issue is recent, I helped change my friends account username a few weeks ago
Issue occurs on both google and Microsoft edge, I do not have any other browsers to test on
UPDATE:
The bug seems to be resolved, I was able to login successfully and change my username.
Resolved invalid as per update in the report description.
