I can no longer control volume from my PowerBeats Pro headphones with my iPhones, works perfectly with my Watches, iPad's, Mac's & so on, worked fine before updating to iOS 13, thought may have been a glitch with 13 but updating to 13.1 hasn't fixed the problem, other than that no sound issues.
I have been having trouble with my PBP's since getting the 11PM. They worked fine with my X just last week but the last two times in the gym I've had connection issues. First the right side would work and the left would just make this weird buzzing sound. The next time the left worked and the right made the buzzing sound. I checked for an update on the beats website but nothing. I don't know if its IOS 13 or what.
