Runner 2 suddenly stopped syncing with my iPhone
Runner 2 is running 1.3.255, iPhone Sports app 4.0.1 (oh, and now the app crashed twice when I go to manage device, about. Make that 3 times in a row)
iPhone 5s is running the lasters version of IOS (10.3.1)
Syncing with a usb cable to my Mac works just fine.
I'm quite used to devices that just work, so I'm very surprised and bit annoyed that my Runner 2 has so many problems (and I only bought it december last year).
Before you add more useless (imho) features (like importing your stepcounts from Apple Health) to the app, please make it more stable and get the basics working.
