Attempted to synchronize Crytomator folders on Google Drive with both Cyberduck and Mountain Duck over multiple days but would fail each time due to Error Code 403, Rate Limit Exceeded. This is identical to the problem described in Ticket 10103, which was marked as "Fixed".

In addition, there were consistent errors finding a couple Cryptomator folders/files on Google Drive even though those do exist.

Appended please find a redacted excerpt from the log.

Thank you in advance for your support!
