AirPods not commanding Audible on new iPhone XR
I just set up my new iPhone XR. My AirPods (generation 1) work fine with Apple music, the double-tap commands working as desired, but not with Audible. I can hear fine, but I can't get them to pause/play (left AirPod) or rewind (right AirPod) with double-taps the way they worked on my iPhone 6s plus. (Again, these commands work fine with music, just not with Audible.) I reset the AirPods (holding in the button on back of the charging case until the light turned white) and reconnected them as if they were new to the phone, but this didn't help with Audible. Any suggestions?
iPhone XR, iOS 12
