Invasive app impossible to remove from IOS Devices

App worked for several months with annoying glitches but it was tolerable. After latest IOS update 10.3.3 and switching to DVR X1 it worked for less than a week. Error codes started appearing and no way of fixing the non-usable app. Completely uninstalled and wiped phone of all traces everything Comcast yet still would. It work. After speaking with level 3 technicians at Comcast for at least 3 hours on 4 separate occasions I was told it was my device. Apple says its not up to them how 3rd parties write their apps. They can only guide to completely wipe my phone and restore it. This is ridiculous that the customer grts stuck between two giant companies who should be able to pinpoint the reason that the xfinity streaming app wont be eradicated. I spent at least 12-15 hours scouring for a solution as Id rather not wipe my phone clean. I wont blame Apple as no other app has gotten into my phone so much that it cant be removed. My username and passwords will not work to connect to Comcast servers via the IOS app on my device yet they work on my desktop pc. Im connected in home just fine so the only thing broken is this app. I made no changes to the phone to cause it to break the app, no new apps were added, I erased all safari web data, cookies, etc and still no go. Restarted many times under different circumstances and still doesnt work. The EULA is not displaying when I reinstall after removing app. I explained this to techs. I know that has something to do with my credentials failing. I even was able to get the safari URL out of the app to launch it on my own! This is a case of problems with programming. I asked the level 3 tech if Im supposed to troubleshoot their code. I offered to email them the URL and they werent interested. Told me to call Apple. Lol Comcast hasnt changed much in the 25 years Ive dealt with them on so many fronts from billing errors to false promises of credits, to service and equipment problems. Hope they get their act together quickly for the sake of their shareholders.
