I found a solution, at least in my case. I also have the Lenovo M10 Gen3 with a similar issue. The dashboard was randomly closing about once a day. I tried disabling different cards without improvement.
My solution is using Fully Kiosk. You have to disable cache:
Settings → Advanced Web Settings → Cache mode → Never use cache.
I also set:
Settings → Web auto Reload → Web auto Reload on idle → 3600.
The second step is optional. I have been running the dashboard for about a week now without crashing. Maybe this helps also to those with Fire tablets and similar issues. I cannot confirm as I don’t own one.
I hope it helps.
