Inbound and outbound connection authorization problem

A bug in the connection update process caused the underlying OAuth data to be invalidated. In total, roughly 25% of connections were affected.

This has now been fixed - any customers still affected by message source or message outbound connections being offline should edit the connection, use the "Authorize" action under the "Name" field and save the form as usual.

Apologies once again to those affected for the inconvenience caused.
