Windows 11 - "Sign in with your Microsoft Account to Continue App Experiences"

This is not by Microsoft, obviously.

Well, I will agree that the Microsoft Store is often not using the latest version of many programs, and one reason I often don't use the Store on purpose.

FWIW, I have been having the exact same issue. I click sign-in and the system tries to log in, I get a white box that looks like a login screen. It pops up 3 times then nothing.

just chiming in, i have the same issue. for SO long i've had microsoft ask me upon logins whether I want to use my personal or a workplace account. apparently at some point for some reason i created a workplace account to test something out and used the same email address I use for my microsoft account.

I always choose personal and the prompt for the "other" is an annoyance but so far hasnt caused me any issue beyond that i know of. I did try to log in via "workplace" here or there to see if i could change or fix something but it always fails/wont work. Makes sense since there never was a workplace but i digress.

either way i now have the same error and every time i click the sign in box I get this

I don't use my MS Account for my computer, only for Microsoft Store
