Do you have enough RAM? Maybe ESPN is a resource hog.Could be, but I never have trouble with anything else. ESPN+ also gets very finicky when I alt tab into other programs while I'm watching.
ESPN+ is better than Fightpass from an overall sporting perspective, but it is worse than Fightpass from a strictly MMA perspective int hat you don't get the library.
The video is pretty high res and stable for me and when I watch, I get on during the prelims and don't mess with it until the end. I had bad experiences from DAZN and don't dare get cutesy and pause or rewind, etc. or close and get back in later. Even trying to jump back 15 sec or whatever might get it to freeze (don't remember which app it was).
When iPod Touch 6 has ESPN+ video stream and computer has Sherdog with some GIF heavy thread, the ESPN+ video will briefly get blurry. This makes me think it's internet bandwidth problem and I have the second cheapest internet speed.
