Apple Music & Strava use on my Apple Watch series 6

Hello, today I went for a run without my phone for the first time. Because I only got my watch yesterday. I have audio cues switched on on STRAVA. But everytime an audio cue came through my Bluetooth headphones it stopped my music. So after every KM I had to resume my music. Please help! I want to just run with my headphones and watch and not my phone but I’ve never had this issue (normally strava plays the audio cue over the music but the music continues in the background)
