I keep getting the message "some services will not be available until you sign in again" and if I click that, I get this and if I click continue, it just sort of hangs. Anyone know what this is?

I've been having the same issue (w/o Dropbox prob) for about a month. Last night, though, I decided to open up Apple Music on MacOS and start making a new playlist. In the middle, it asked me for my AppleID. I punched it in, and no more problems. For now at least.
