Yes, mine was working properly for at least 2 years until the EERO router update this pasty week. As soon as I turn OFF the ad-blocker in my router Paramount+ worked properly again.
I don’t understand how that could be since my other TV uses the same wifi and does not have a problem and it’s been working fine. The TCL with Roku built-in is the problem. The standalone Roku on my other television is fine and I can watch no problem.
I never had ad blocker on my Planet Networks modem/router and according to them there hasn't been any recent updates.
I am using the Roku Stick and am having the same issue. Paramount Plus loads up fine on our other two tvs that is using the Apple TV. The thing is this wasn’t an issue a while back has just seem to have started last couple months. If we want to want paramount plus on our tv with The Roku stick we have to air play it every time.
