I really don't know what category to select for this.
I am on a free account. I logged in and I can't open any folder or file. The storage is only about 50% full. I get this message:
Something went wrong. Don`t worry, your files are still safe and the Dropbox team has been notified. Check out our Status Page to see if there is a known incident, our Help center and forums for help, or head back to home.
No issues are reported on the Status Page and I tried some suggestions from the forums. I use Edge, with windows updates on. I tried clearing the cookies or incognito mode, nothing changed.
