App freezes can’t get out of it have to delete it and reinstall it

Sick of Xfinity app freezing up while watching sporting events. Can’t do anything with the app have to delete it and reinstall it and then miss what happens. Lately keep my laptop close so I can watch the event while reinstalling the app. Just downloaded ESPN so I don’t have to use Xfinity I guess time to cancel Xfinity T V.
