Hi,
I’ve been setting up some permissions restrictions using flow rules to block access to some group folder sub folders. What I have noticed is that if a user has already downloaded some files through the sync client, and then they are blocked, the previously synced files remain on their local machine. I assume that the blocked files cannot be synced from then on, but ideally the client would check access permissions and evict local copies of anything the logged in user no longer has access to.
I had to remove the account from the computer and then add it again to make sure the NextCloud local directories reflected that of the server flow rules.
Cheers,
Spikey
