I enabled that in /var/snap/nextcloud/current/nextcloud/config/config.php with ‘filesystem_check_changes’ => 1,, but it did not fix the issue. It did seem to remove one error that was popping up, but I am still getting a prompt stating that the file could not be created (which is strange because, when I did a file scan, it shows that they were created), and the files are still not displayed.
It should also be noted that I restart nextcloud after applying the changes with # snap restart nextcloud.
