ph360, if you are in the fast ring and on 14291, you are having two choices:
- wait until there is a build fixing it
- reset device with WDRT and go back to TH branch. Stay out of the RS branch (so slow or preprod ATM, but this can and will change) and update it until you are at 10586.164.
mymarcio, you are on the most current build, there is no newer OS version in the fast ring ATM. The reboot is normal. Check your setup in the about screen - but as you are on 14291, you ARE in the fast ring, otherwise you would not have it. You are not affected by this bug from a specific build from last year.
Please be aware, that the fast ring builds can and WILL have issues. It is a rough place. And it is often stated, that it is. Also, it is voluntary.
