I have an iPhone 7 and a series 3 (GPS) and I am also an Apple Music subscriber. With that being said I was on a run last week and was streaming a playlist that I had downloaded to my iPhone and skipping some of the songs via my watch but for some reason some of the songs seemed to buffer if you will until I went back to home screen and went back in music app. This was super frustrating as you can imagine when I am trying to keep a certain pace on my run. So I decided to sync/download the playlist directly onto my Apple Watch and see if that solves the problem. I figured that since my running route is close (depending on which route I take) to my house maybe it was going in and out of my WiFi and then going to Bluetooth. Well downloading to my watch worked perfect however when I went to download/sync another playlist from my iPhone directly onto my watch it seems to be taking forever? Does anyone else ever have this issue? Side note: I am coming from a series one and didn’t realize I could control my music from my phone on my watch due to me being an Apple Music subscriber.
