Since a few months now, I have this issue where I physically cannot log into my account using the Roblox App from Microsoft Store.
When I press the ‘Log In’ button, the app just loads infinitely, unallowing me to log in.
Here is a video of the footage.

Please let me know if you also have this issue.
If you managed to fix it, please tell me how 
use the chrome version instead of microsoft store version
Yeah but, I need to use the Microsoft Store one to play on 2 accounts at the same time.
try reinstalling roblox from the microsoft store maybe it’ll work
I already tried in the past, but I’ll try again right now.
Edit: Yep still doesn’t work…
idk how to fix it sorry brother
You can always use Bloxstrap which allows you to run multiple roblox instances/games at once
I didn’t know that existed. Thanks
