It is useful to have alert notification of failed workflows sent to members of group put as workflow owners, currently groups are not supported for alerting (that's the answer I got from support).
Groups as workflow owners simplify the management of workflow authorization and should be supported as recipient for alerting
This feature has now been released - closing ticket.
Wish we could configure these Alert notification at workflow level instead of tenant level.
We were advised this was planned, can someone confirm? If so, when is the ETA?
