Worst functioning app ever

I used to enjoy this app, but now nothing works and I have xfinitys supposed fastest internet speed. Total garbage nothing loads and when I launch the app it freezes. If you are going to make an app, have it work. I am connected with my home wifi and still nothing. Troubleshooting is all garbage too. Need to rethink how to make this app work before making promises!
