Today I had to change password because of data breach. Upon doing so I could no longer log from my Ipad to the App XFinity TV (no problem logging from PC). I did all the normal stuff, clear cache, uninstall-reinstall, reboot etc. Nothing worked and no answers--so I (reluctantly) upgraded my IOS to 10.3 (above 9 needed to download the newer app) and then downloaded the Stream App which connected effortlessley. Something killed my legacy compatibility today--not for me to figure out--just posting here to save anybody else also pulling out hair.
