it’s all good! Just wanted to share my experience with this tech. I am not a networking expert at all - just a tinkerer and a lifehacker who is a sucker for simple and elegant solutions. I am not above putting in some elbow grease when necessary though (like when I had to painstakingly modify coffeescript code in my Ubersicht widgets to make them just right without knowing anything about coffeescript haha)
So the thing is, my dad pays for Bell Fibe Internet and TV and when I am on LAN, I can watch all the channels that the subscription includes from virtually ANY device (firesticks, iphones, androids, laptops, etc.) either by downloading the Bell Fibe TV app from the appstore or by going to https://tv.bell.ca/home. Bell detects automatically that I am connected to the internet through them, as well as my dad’s subscription (no need to log in or anything). I can trick Bell into thinking that I am at home by running a funnel on my server with the help of Tailscale. Now, when I am away from home, the app will only work when I am on wifi AND connected to Tailscale AND using my server at the exit node (funnel). If I am on cellular, I have to use the website I mentioned earlier. The best browsers for that are Samsung Internet on android and Grazing 3 on iOS, since they allow the picture to fill the entire screen. In principle, you should be able to access your subscription from any device that has a web browser and can run Tailscale.
