Power BI subscription error notification please!

Recently, I ran into an issue where my subscription to users via email was failing and I hadn't a clue why. My report was relatively unchanged from the prior version, i had changed the theme, added a background picture, and changed some of the visuals. Nothing too crazy right?! Well i spent a day digging around why, when i setup a subscription, and tried to send out the email, it never arrived. In addition to that the subscription was also turned off, but not by me?? I checked the prior versions of the report, settings, in desktop and also service, but nothing seemed out of the ordinary. Turns out the problem was with the background picture i added. It was too large. What is super frustrating is there is no notification that this was a problem ever!  Microsoft, please put an error message on things like this. I have to scroll through forums, settings, and just pull my hair out, when all you have to do is put an error message somewhere, hell ANYWHERE to tell a user why something is not working!
