No audio prompts through phone

I recently received my Epix 2 as an upgrade from my old Forerunner 945. After a couple of runs I noticed that I'm no longer hearing audio prompts on each lap. I always run/bike/walk with airpod pros connected to my iphone listening to podcasts or music. Sometimes with maps navigation as well. On the fr945 this combination always worked. 

Here's everything I've tried:

1) toggling the prompts settings off/on with syncs in between

2) rebooting the watch and phone

3) re-pairing multiple times

4) re-installing garmin connect on my iphone

5) connecting airpod pros directly to the watch (this does make audio prompts work, but it's not how I want to use them)

6) connecting watch to garmin express on my computer and updating watch + maps

7) resetting watch to default settings

8) manual laps via button press and auto laps (neither work)

Has anyone else experienced this? Did I miss any troubleshooting steps I should try? Should I try anything in particular again to double check? 

I doubt it matters, but:
