I've seen a lot of different issues here that sound a bit similar, but different.
I'm using Fully Kiosk and Sharptools for several (7) fire tablets. They all work just like I would expect....except.
While all "things" seem to update correctly, I have one in my bedroom and another in my office that I want to run the screensaver and set the screen brightness to basically off at night.
They work fine if I've been using the tablet...but I just get 408 messages back from often...not always...when I try to set this in a rule.
I've done everything I can find to keep the wireless up that I find on the Internet/You Tube...all the battery saving and developer stuff but must just be missing something.
Any help/suggestions would be great!
