Multiple account problems on Mac

<!--- I do have the same problem as some other users, "multiple accounts are sharing the same folder ..." I followed the steps in the FAQs and the solution of previous posts and deleted old sync files from the local machine as well as from the server. There have been a few older db file versions but they are now gone. Desktop and server versions are up to date, the latest release for both . Mac OS 12.2.1 Monterry This is what I tried and checked. Did not deliver any result https://doc.owncloud.com/desktop/2.10/faq.html#error-messages https://central.owncloud.org/t/problems-adding-folders-to-my-desktop-client/34512
