Not true but I’m glad yours is working.
Pluto continuously goes out regardless of what channel you’re watching BUT the stand alone channel (NewsMax, etc) works on Roku without disruption.
I know, it sounds strange but it happens all the time. Have uninstalled, reinstalled, and so on.
I have pretty much Zero problems with Pluto on ROKU except needs a regular Bi-Weekly unplug to reset itself.
Do you reset / reboot your router regularly, say once a week?
That’s a must. This cleans up the router and forces all your connections to reset too.
