The history purchase shows app my husband didn’t even download..

Hello everyone.

The thing is my husband discovered app like Tinder, Bumble, and other erotic app on his app purchase but not all at the sime time and other games and app he never downloaded. He received on Friday a text registration confirmation for Bumble out of nowhere, and when we went to the history, nothing was downloaded on Friday so it can’t be him and I was near him when it happened and the last time they showed the app was downloaded it’s 1 year ago.. and that’s how we saw the other app, I didn’t believed him at first but the more we saw some other app, the more I knew it wasn’t my husband since there’s stuff like Pokemon or American dollars or Sudoku and other stuff that aren’t my husband type of app.

He also have weird Facebook videos on his Fb notifications black color that he can’t open at all, we tried and it didn’t work.

How it’s possible? There’s no other device connected. I also have some app in the history I didn’t remember downloading at all.

Anyone knows why or how can we fix this?
