Soundcore A1 glitches when playing from Garmin Fenix 7

After around 10 min of playing off Garmin Fenix 7, sound interrupts repeatedly at random intervals for split second, happens to both buds.
I’d love to have this fixed cause I really like the product

Same with Garmin forerunner 255. After 10-15 min the connection gets instabile. Manual disconnect/reconnect helps for another 10min, but is very annoying. Other BT inears seem to Work with Garmin. Otherwise great headphones for jogging.

I have swapped them with Sony WF-C500 now. They work fine with Garmin Forerunner 255.
