App appeared that I did not download

The iPhone is password protected, and I use Touch ID, no one else has access.

The Apple ID is not shared, also no family sharing.

I also know how to delete apps.

It is a mystery as to how it got on the iPhone.

I do subscribe to Netflix, the maker of the game.

The only change I have made recently is to add a South Park game that required signing in to Game Center, something I’d rather not use since I have no interest in multiplayer games.

Any thoughts?

Thanks for following up, that is actually what concerned me, it appeared on the first screen that had an empty position. Which was two away from home screen. I very rarely watch Netflix on the phone, usually on the iPad.

I only do manual updates, no background updates. I’ve been an iPhone user since the 3GS, and I’ve never seen a third party app just appear before.

The only recent changes to any settings was turning on game Center. I wonder if that had anything to do with it, or if it slipped in with the last Netflix update. And I have not watched that show on Netflix.

It just seems a little too unusual, Which is why I am bringing it to the forum. I wonder has anyone else experienced something like this?

Thanks again for your help!
