Ditto with this. I'm using the ios10 public beta 4. After I updated iOS to the latest version last night I checked everything was working, but the app update this morning has broken it. The app launches and immediately crashes back to the home screen. Tried re-booting, uninstalled reinstalled etc.
There is a bug with iOS10 that's causing the app to break. We've implemented a fix today, and are going to run through a thorough test internally before releasing it out publicly.
It should be noted this isn't an issue with the app, but more so the OS beta. Which isn't uncommon (it's Beta for a reason, lol). While we cant claim to truly support beta versions of iOS, our fix for this particular bug will actually put us in a better place for future updates -(future proofing, if you will), so while it was unexpected and obviously frustrating for those of you who didn't expect it to break, it will benefit us in the long scheme of things.
