Constantly refreshes whether I'm watching in SD or in HDX. Update your app and fix these refreshing issues. My tablet is compatible with HDX. If it wasn't, it would say so as it did on my old generic tablet. It never refreshed this much on that one. Oh and fix the crashing problem too. My HDX compatible tablet is a Samsung Galaxy Tab A 10. No issues on my phone but the screen is too small to enjoy anything other than a cartoon.
