I just installed Cryptomator and created a vault in a Google Backup+Sync folder on a Trucrypt volume on a Windows 7 system and I have the following problem:
After giving a second person co-editor-permissions with Google it is not possible to delete folders from the vault-drive. Deleting files works as is should. The folders dissapear when I delete them but when I click on an other drive and come back again they are there again. When I revoke the permissions of the second person in Goolge I can delete the folders.
Reinstalling and recreating Cryptomator and the vault did not solve this problem.
