We have had two instances in the past couple of months where two different Dataflows which were scheduled daily became unscheduled. No alerts in email, nothing in the Admin Audit file.
Has anyone seen this?
I have not raised a Case at yet, as I have no evidence or trail.
I have not found anything in the Googleverse, except an known issue when the last updater user account is deactivated, which was not the case here.
