I decided to switch to another platform for sync (OneDrive) and so far everything is working well.

Thank-you for your reply. No, this was not the case. I did not change the password. The sync spontaneously stopped working on all my devices. I will try to switch my sync platform from Dropbox to OneDrive. I prefer Dropbox however.

Today suddenly Enpass on MacOS Big Sur, iOS & Windows 10 will not sync with Dropbox. I get an error message 'Password of data on Dropbox is required'. Same on all devices. I enter my password with no effect. I changed the password as prompted with still no effect. Anyone else having this problem? I can sign in to my Dropbox account with no problem and Dropbox shows all features and systems working.
