We've been creating a distributed collaboration between AGOL and Portal, with services from Portal being sent over to AGOL as copies (so we can make them public past the firewall).
Twice now - the services that were in the collab group on Portal have just disappeared out of the group. The services are still active, just not in the group anymore. In AGOL, the feature layers are still there, since they are just copies, but they are no longer being synced.
Any clue what is going on?
