Sync of Recordings working intermittently

[NBizzell]

We have several classes using this plugin, some seem to sync all of the videos fine, others have stopped after a number of sessions and the refuse to sync new videos after that.

when a sync is attempted it appears to start, however there are no changes to the list of recordings and the date of last sync does not change.

We are using the latest version of the plugin. The user syncing is the same as the meeting organiser.
