Someone sent me a shared file in dropbox. Tried to download and open file. Kept asking for me to log in with Microsoft account, which I did, but kept saying password is incorrect (IT IS CORRECT). I even created a dropbox account. Even from within dropbox, try to open pdf file and it makes me log in. Again, says Microsoft account password is not correct.
I used to be a dropbox user and dropped it because of BS like this. I see nothing has changed.
