Delete game data from phone
So I'm playing the game dancing line and I want to start over. I was told if you go into settings, iPhone storage and delete the app that way it will work, however when I tried it recently still keeps my data. I've try to get rid of any data from iCloud but that doesn't work either. It might be the game but I'm not sure. Any help would be appreciated. Thank you!
iPhone 11, iOS 13
