Okay so I have this weird problem. When my iPhone X (iOS 11.1) is connected to my car's bluetooth and my airpods together, the audio on phone calls seems to cut out every second or half second and come back on. Music is fine. I have to disable my car's bluetooth for the problem to resolve. This issue did not occur on my iPhone 7. Any suggestions on what I can do to solve this? I already repaired the airpods to the phone.
