My vote would be firmware too based on the issues described. (But I've been wrong here before)
OTOH - It might may be a defective display or a perhaps power issue going to the display.
Truth is, we could all be guessing here forever...and it would only be just that! (guessing)
I think it best we allow Kemper Eng to weigh in with both their product expertise and knowledge.
I'd like to believe they'll convey something to us as I'm sure it's a colossal high priority to get this resolved and restore product confidence.
Sadly, I'm really kind of torn now...
In as much as I'm anxious for receipt, I would much prefer to have greater confidence in receiving a trouble-free product.
So, as frustratingly as all this may be, Kemper is being wise slowing delivery until the root cause is identified, resolved and then stabilized.
Got to believe the resulting solution will too be a relief for those currently having no reported issues.
The end results being:
1) Improved product confidence for all of us,
2) Improved/salvaged reputation for Kemper,
For me, I'm still keeping the faith,
I also remain committed but maybe ought to start thinking about being committed. LOL
