I got a problem when attempting to update to 10586.36. I have been an insider for a year and everything just fine for the past. I was using 930 before. Every time it had insider update, I got and installed without any problem. Now I am using 950xl. When I tried to update to .36, problem occurred. The update progress stuck in 0% for long long time. Even worse, the insider app seems to cause battery drain. I tried log out from insider program, but failed. It said the insider app is updating and can't take any change. I then uninstall the insider app and restart the phone. I checked that the insider app had gone, can't be seen in the app list. Then I go to settings abd check for update. I see there is an update for insider fast ring. What happened!? I have no clue to tackle this. Finally I factory reset the phone.
