This has been going on for two days now.
Latest Roku software is installed and the TV is wired directly to my modem. Everything else in the house works fine. Netflix, Prime, YouTube, Pluto etc... every app kinda does the same thing; it'll load to the app's homepage but no specific show will load. No error messages. Tried connecting wirelessly and it's the same problem.
Hoping someone has a great suggestion.
First, have you tried restarting your TV from Settings->System->Power? Second, restart all of your network equipment - gateway/modem/router.
If nothing works, it points to a problem with your network even if every other connected device you have is working.
I appreciate the quick responses; thank you.
I think I found the solution just minutes after posting, however, I was running out the door. Settings>System>Advanced>Network Connection Reset seems to have fixed the problem. Everything is loading again.
Hopefully that's the end of this odd hiccup.
