Find My Friends has disappeared

Find My Friends has disappeared from my iPhone 8 after the last update. The icon is gone, it is gone from my purchased list, and in the App Store there is not an icon that is the same as the one I had. All of the Find type apps say Get instead of open, which is what it should say since I already had the app.

I still have it on my iPad, but totally disappeared from my iPhone. How do I get it back?
