Live TV does not work in Guest Mode
I have five TCL Roku TVs at a vacation rental property - all are in Guest Mode.
I have a Roku Streaming Stick here at home. I also have a much older Roku at another location.
All devices exhibit the exact same behavior below.
When devices are in Guest Mode, and ONLY when they are in Guest Mode, no "Live TV" channels work. The error message is simply "There is a problem connecting to the network. Please check your network settings." with no error code.
However, I can install other channels (youtube, plex, etc) just fine and they work fine.
If I disable Guest Mode, Live TV works fine.
I started a support chat and the only suggestions were to restart my routers (at three locations?) and reset the network connections on the Roku devices. Obviously, that's not the problem.
As an aside - I noticed when installing Plex in Guest Mode that it doesn't allow me to 'activate' using a sign-in on my mobile device - the error that comes up says something along the lines of 'this is not supported in guest mode', and I have to sign in using the plex app on Roku using username/password. Perhaps related or perhaps not, but it's also an issue with Guest Mode. I think I remember seeing this with Pandora, too.
