Bro my Xbox app won't let me sign in, I keep clicking sign in but it does NOTHING and it's...

I have a problem with signing in to Minecraft with my Microsoft account. Every time I click sign in, it brings me to the "Let's get you signed in with XBOX Live" screen. I click sign in and it brings me to a confirm
page to confirm my Microsoft account. I click "continue" and it brings me back to the "Let's get you signed in with XBOX Live" screen. I clicked sign in and it brought me the confirm page again. I clicked continue and it brought me back to the Minecraft app
but the screen won't load and the app is stuck on a black screen. Is there a solution to this? I've tried uninstalling and I've tried to disconnecting my WiFi from my Android phone.

Xbox one won't let me sign in at all on any profiles at all and it doesn't pop up any errors and when I click on my account to sign in it won't do anything it just goes back to the home and won't sign in.

ive tired to do all of the suggestions but my xbox wont let me sign in after i sign out. it would ask for my password then comes to a screen saying "this account has already been added" acting like i never signed out and i keep clicking connect to xbox live
and the screen would just sit there and do NOTHING

No iv already tried that but it keeps saying it won't let me log on it from his xbox like my profile will download but it won't sign me in on it

for me the xbox beta PC app will open and when I click sign in, it signs me in with the correct account, and then I close the pop up window and the app is not signed in. I can hover over the sign in drop down and do it 500 times but it never actually lets
me sign in.
