I assume part of the problem has to do with the local Verizon tower bandwidth. We use a Verizon jetpack hotspot for our wifi connection. Our town, being a tourist spot, gets busy at times and the Verizon tower gets loaded down.
When it's like that I cannot get into the PBS passport channel. I can view other channels like Netflix, Disney, Britbox, etc. PBS Passport seems to time out and it just goes back to the home screen.
Is there some kind of a timeout you can adjust?
