Hi jim9976,

Welcome to Apple Support Communities! We're glad you've reached out for help with updating your app. We're glad to point you in the right direction.

Are you encountering an issue opening your app? If it's indicating that the app isn't compatible with your version of iOS, you'll want to check the App Store for updates, or for a newer version of the app.
