Installed iOS 10 Beta 1 last night under a dev account, installation went perfect on the phone (6s). Went through the OS for about an hour and a half, everything worked pretty fine (apart from the occasional slight lag and lower than usual frame rates when closing/switching apps etc). Woke up this morning, and the phone became pretty much unusable suddenly, I can hardly get messages or even whatsapp to work, can't type anything, apps keep crashing. Anyone know why? (please don't say it is a beta and this is expected, I know it is but my question is why did it work fine yesterday and not today? - or if someone knows what is causing this)
