Cannot stop Update Software message from coming up
Roku Ultra, model number 4670X, Software Version 18.104.22.16807.
I have an odd thing that started to happen a week ago out of nowhere. About 5-10 seconds after I turn everything on, wherever I happen to be in the Roku system (home screen, Netflix, wherever), I get a light-grey box showing on the screen that says, "The latest version of the software is available for your TV. Do you want to update now? (Version 04.71.30)." Below that wording is a No and a Yes button. But there is no way to select or click either of those buttons.
This message goes away after about two minutes.
I did go to my Settings and request a software update, but it is up to date already.
