Running 9.3b2 with a brand new 6s on T-Mobile. The Ookla Speedtest app seems to crash every single time I try to run a test with wifi off. If wifi is on, it works just fine. Have deleted, reinstalled, reset network settings etc...no dice. I did notice that while on cellular, the speed test app automatically selects a server in Bellevue Washington hosted by T-Mobile. Even if I change the server though, as soon as I try to tap 'Begin Test', the app crashes when on cellular. Is anyone else experiencing this?
