Another thread going on here https://community.roku.com/t5/Community-discussions/Roku-disables-player-with-attempt-to-coerce-arbitration-agreement/td-p/950649.
atc98092 indicated pressing the Home button on the remote a few times worked to exit this screen without agreeing.
I saw a few online postings that restarting the network also helped clear this from the screen when this first started happening a few days ago.
This explains why I haven't seen it. My Harmony macros make extensive use of Home since that "resets" the state of the menu to the top, putting it in a known state for macros.
