Is the Google Pixel 2 compatible with Roku TVs for mirror screening?
[post moved to appropriate board]
@T_Washines Thanks for reaching out! Google branded Android devices (Pixel, etc.) no longer support the protocol required for screen mirroring on your Roku device.
Other brands of Android devices should still support the feature. You can see more here: https://support.roku.com/article/208754928-how-do-i-use-screen-mirroring-with-my-android-or-windows-...

My pixil does cast YouTube to my tv, but will notcast a Facebook video. What's the issue?
YouTube only casts because there is an in-built YouTube app on Roku. There is no Facebook app on Roku, so videos cannot be cast.
Google have removed compatibility for Pixel phones to screen-mirror with anything other than Chromecast devices.
I have a TCL R635 and a Google Pixel 3a. Here's how I got Cast working: Install the Roku remote app onto your Pixel. Start it, detect and connect to your Roku TV, leave run in the background. Start YouTube and now there's a CAST icon. Boom done!
You are casting youtube. you are not mirroring the screen.
