IMO no 3rd party app is worth using on those devices.

My parents pay over $300/mo for an Xfinity bundle. It includes everything (phone, internet, and all streaming services on one bill)

The paramount+ app on the Xfinity box took TEN MINUTES to load a show. This is after crashing three times back to the logo.

Xfinity warns that it’s a 3P app and they aren’t responsible for it but it should be criminal to take the money and subject elderly people to this under spec hardware. Even live sports will pause and stutter.
