Paramount+ black screen when trying to playback

Let’s get your Paramount+ back up and running, @Wpixley. This How can I fix streaming issues on my device? covers the most common fixes for streaming issues like the one you're seeing. If that doesn't help, let us know, so we can further assist. Charles, DIRECTV Community Team

Uninstall/reinstall the app. Also--restart the device.

I have uninstalled the app and reinstalled, unplugged and plugged back in the Gemini, switched HDMI cables, cleared the app cache and data, and unplugged my modem and router. ALL other apps stream just fine, just Paramiunt+ gives me a black screen when I choose a program to watch. The app loads, I can browse and even watch previews, but if I select any program to watch (stream), all I get is a black screen. DirecTV is now telling me to contact support at Paramount+. 

Meet us in a DM, we have a specialist who can look into this further for you. Charles, DIRECTV Community Team

Paramount Plus app working fine for me on my Gemini box and Gemini air

Solution Found

I have an eero router and I found out in the router setting that Ad Blocking was on by default (maybe via an update or something). I unchecked the box next to Ad Blocking and now Paramount+ streams just fine. 
Problem solved! 

Glad you're back up and running! Thanks for the heads-up. Rhyan, DIRECTV Community Team
