Yes I did a hard reset. But I am on PB 10.3. I have to wait until Apple releases 10.3 to the public before Apple can do anything to fix it.I'm on iOS 10.2.1. For me the problem started after I erased my phone and restored a backup. This morning was the first time I've had transcription work in over 6 weeks.
Did you turn you left phone off and on before testing? It didn't work for me until I did that.
