Deleted app not fully deleting
One specific app constantly reappears as a grey-ed out block when I reset the phone. I can't open it or do anything. When I delete it from there again, it is 'gone', but still shows up in a search and in the settings menu, although I can't open it. If I go to the app store to download it again, it shows the 'open' button, but nothing happens when you press it. So it isn't there, but it is, and I can't delete it fully, nor re-download.
I have hard reset several times.
iPhone SE, iOS 15
