The strangest thing: since I upgraded from iPhone SE 2016 to iPhone SE 2020 I no longer hear the audio prompts.
Before upgrade I set up my activities to give me a tempo update every 5 minutes and they worked just as expected.
Now, no matter the activity I get no audio prompts any more. But here's the kicker: if I play music, the music gets surpressed every 5 mins (like also happened with my old iPhone) but no audio prompt! So (I gather) it is working ALMOST like it should...
firmware: 6.20.0.0
Any suggestions?
