Airpods connect/disconnect to iPhone

I recently got a Fenix 8 47 mm AMOLED and really love it HOWEVER, for some reason my Airpods have stopped working with my iphone. I do not want to connect the airpods to the watch and haven'r done so eather, but not when I want to use the airpods with my phone, they keep connecting and disconnecting instantly. I know its the garmin watch / app spooking because they work perfect when the watch is disconnected. 

I have also tried resetting the airpod connection with my iphone but with the same results.

Anyone else experienced this and know how to solve it?
