UpdateGroupSubscriptions should throw an exception and log an error if a contact cannot be subscribed or unsubscribed to groups
Action, UpdateGroupSubscriptions should throw an exception and log an error if a contact cannot be subscribed or unsubscribed to groups.
This is an important error to catch. For example, if website has a "subscribe to our mailing list" form which is not actually adding contacts to a mailing list, then this should be fixed. Otherwise the mailing list is useless.
