Random refresh failure and no email notification of refresh failure

We have noticed the same thing.  I posted about it a while ago.  This isn't new.  I think part of the issue is that we (users & admins) are expecting notices on all failures (like we would have in other programs, ex. SharePoint).  But PBI is only coded to send messages when certain unattended refreshes fail.  That is short sighted.  And even that doesn't always work.  I've probably had 100+ failures during testing.  I've received about 5 or 6 failure notices. 

Microsoft, please set this up so that ALL failures trigger a message.  Even better if you could put together reports for the admin portal on refreshes.  I have a library of reports and alerts for my SharePoint on prem setup.  I would be happy to show them to your developers so you can understand what sort of information IT departments want to track.
