First of all I like to say that I like the new audio prompts where it is more descriptive on lap paces and next steps in the training.
I'm currently halfway through a Garmin coach 10km workout. I typically listen to Spotify via phone and the audio prompts will be linked to my phone and then send over to the headphones. The following is what's been happening the past 4 days,
Monday. Running with new software ver 17.20. Audio prompts stopped working after about 15 mins. Later in the evening started a strength training workout and Garmin audio prompts started voicing out all steps done on the earlier run. Went on non stop for about a minute
Tue. Same thing happened on a Garmin coach run. At the end of an hour run the Epix gen2 did a soft reset on it's own. Still recorded my total run but all the lap paces info is not recorded.
Wed. Decided not to use Garmin coach and went for normal run. Audio prompts seem to be working fine.
Thu. Did speed repeat on Garmin coach. After about 15 minutes audio prompts don't work anymore
