I was able to fix it. Click system, then click power, and click system restart. Once it rebooted it was gone.
Works fine now, thank you.
I did a restart of my Roku and it went away.
I forced update, it said updating engine took 2 seconds fixed it.
I am having the same issue
I restarted and the app was still initially there for about 1 minute and then it disappeared. Hope it's not a virus but just a glitch.
Same thing happened to me
I noticed my apps were not organized the way I like them and then I saw it and I clicked on it and nothing happened and then I updated the app and it disappeared. Rum Microsite Roku and there was a picture of a rocket on the app
I clicked on and it showed Roku deals. It was obviously a code some developer was playing with but made it live by accident
This happened to me today only way I got rid of it was on Home select options button on remote and then select update. I believe this has something to do with advertising.
