How Can I Find My App In The Store?

The links to your app are available in your Developer Account. It's best to check your Developer Account for the links because you'll also be able to see if Apple or Google took your app out of the store for some reason. Apple charges $99/year for your Developer Account and if you don't pay, they immediately take your app out of the store.

To check your Google Developer Account, go to https://play.google.com/console/u/0/developers

To check your Apple Developer Account, go to https://appstoreconnect.apple.com
