I had .164 on my 928. Upgraded to .318 and it broke my cellular data. Restored via WDRT to 8.1, then attempted to get back onto W10, but I only was able to get .107 which deprived the 928 of audible notifications...kinda important. When I tried to advance beyond .107 in Windows Insider, the app told me I had no path forward. So I restored back to 8.1 again and have pretty much given up on W10 for this device.
It's a real pity, because the 928 on .164 was *very* good. Guess I should have left well enough alone!
