Indeed. Much like this request, I feel like this could really help users see immediately what is wrong. They may not need to understand why, but it is a least a visual indicator that SOMETHING is wrong. Also something to clue support into really quickly when screenshots are provided.
And would go perfectly with this feature request for more information added to the diagnostics screen.
User experience is very important. Yarbo has one of the nicest apps I’ve seen in the industry so far. This would certainly enhance it.
