Xfinity streaming service requires login everytime I use it (Apple TV)

I just got the Ultimate Channel Package with Xfinity along with Gig internet and pay over 300 a month for this service. I have called customer support many times but they always tell me someone will get back to me but no one ever does, so I'm trying one more time before I just cancel. 

I have two apple TV's in my home connected directly to my router internet. When I open Apple TV all my other apps work fine and don't require me to login on every use like (Hulu, Netflix, Sling, Disney+, ESPN..etc). However, when I click on Xfinity stream app, it requires me to do the QR code and login from cell phone everytime I anyone in the home wants to use it. When I'm at work my wife and kids can't access xfinity stream because I"m not there with my cell phone to do the QR code and activation pin number while having to login into my xfinity account via the web just to use it. I was told that as long as I'm using xfinity stream on via my internet service I wouldn't have to do that. Both Apple TV's are directly connected to my router via CAT cable. I feel like I'm wasting a bunch of money because the only person who can watch it is the person with the cell phone and account information present to activate it can use it. I can't get to my phone everytime it rings while I"m at work just so my wife and kids can watch TV from inside our house. Weird thing is if I use the xfinity stream app on my phone it doesn't require constant login, nor does it require it on my computer or ipads. Just the apple TV's, which is weird because we only watch TV on our TV's not computers, phones and ipads. 

Things I have tried:
Called tech support three times spending over two hours each time where they put me on all types of trouble shooting which include:

1. Turning off two step verification

2. Deleting the app from all my devices (cell phones, Apple TV's, Ipads, computer, laptop)

3. Logging out of my account on all other devices.

4. redownloading and relogging in to the apps.

5. Restting my wifi router

6. Changing out my wifi router (required me going to xfinity store to replace the router, even though I had no issues with the internet or access all my other apps on my apple TV)

7. Connecting the Apple TV's via wifi instead of directly plugged into router and vice versa. 
8. Made sure all drivers and software updates are installed on Apple TV. (Apple TV's are 4K 2021 Apple TV's)

When I was sold the service I wasn't told that only the person with the cell phone the account can log into the xfinity streaming service in the home for every tv and everytime you want to watch it. 

We don't logout of the app after use, so it should keep us signed in like all the other apps we use (Netflix, Hulu, Sling, Disney+..etc) 

Anyone got a solution for this? Its annoying and defeats the purpose of why we purchased the service. No one can watch TV but me because I'm the only one who can use the QR code and login to my account via the web browser and my wife doesn't want to have to deal with that and when my kids get home from school they can't simply turn on the TV and watch like a normal cable TV service is suppose to do. Its frustrating. I have been told several times that someone will contact me that is higher up in the tech support chain, but I never get that phone call back. 

When I do call its always the same call center and it doesn't matter if you are seeking sales or tech support its all the same people in the same building. If I'm on the phone with one "tech support" person and they literally read a script and have me unplug this, delete that, reset password, turn off and turn on two step verification..once they realize they can't fix it they say they are "transferring" you to a higher up person in tech support when in reality its just another person three cubicals down in the sales department who makes you do all the other things the last person made you do. Once they realize they can't fix it they start lying to you, for example I was told "This is a standard feature of xfinity stream that all xfinity stream apps require device activation and login everytime you use it". Then you are told that they will notate the account and someone will call you. Its a merry go round of hours and hours of nonsense of the same people doing the same thing over and over getting to no solution. Its rediculous that they do this to Xfinity customers. This is my last attempt to get this issued resolved and find a solution before I just give up and go with a different company.
