Fit XR keeps stalling at exactly the same place in a boxing class saying its the internet connection but plays other classes all the way through. I feel like it is a glitch being blamed on internet connection. What can be done about this? I find Fit XR extremely gliltchy. Constantly stops a few minutes in but then sometimes it play with no problems. I dont want to get rid of it because its great when it works but dont think i should be charged subscription when it doesnt work that well.
