Course owner invitations

[ShaunNeighbourSwale]

Not sure if this is GAM or Google, but owner invitations have gone a bit mad.

Updating a course owner with "gam update course ####### owner fred@fred.com" appears to work, but any subsequent requests to change the owner results in the message;

"Course: ###########, Update Failed: @OwnershipTransferInProgress Ownership of this class is already being transferred"

I can see the "pending" invitations, although these are in fact complete, as the new owner already has the course (according to "GAM info course ##########"

Any ideas?

Just to add, the affected course shows no pending invitations;
