Not sure if anyone else has experienced being forced to change their iPhone passcode since upgrading to 8.4? (my iPhone is not affiliated with work exchange servers or profiles, which can cause this) but i was this morning for the first time ever on my personal iPhone.... I was then asked to log into icloud again and this failed several times (probably due to the fact as i was connected, or not properly connected, to the subway systems wi-fi). Result = account locked out for 24 hours and me ranting to Apple CS. Anyway, that another story.... just seems odd to be asked to change my passcode... anyone else had this since upgrading?
