Countdown Timer Repeat Timer on Apple Watch Stops Music Playing

9/26/19 -

I have been using my Apple Watch Series 3, with my iPhone 8 and Apple Airpods for the past year during my workouts. My normal routine:

- Start Sirius XM App or Apple Music on my iPhone, playing through my Airpods

- Start Apple Watch Workout App (Strength Training)

- Start Apple Watch Countdown timer (which notifies me with alert when interval done, then I press "repeat").

This has worked with no issues, ONCE I PLACED WATCH IN AIRPLANE MODE. Yesterday, I updated my iPhone 8 to iOS 13.1, and my Apple Watch to Watch OS 6.

Working out this morning, every time my countdown timer ended, the music would pause. I would then have to press "repeat" on the timer, but then switch over to music and press "play" to resume music. Very frustrating to say the least.

So far to troubleshoot after reading suggestions online, I have:

- Placed Watch in Airplane mode (this used to work, no longer does on Watch OS 6 and iOS 13.1)

- Unpaired, then repaired my Airpods

- Turned off "Push Alerts from iPhone" on my Apple Watch settings

- Tested using only countdown timer and music (and not running strength training app)

Nothing has worked. Any suggestions?
