Can't migrate an existing app to a new iPhone
I want to migrate an app (Pearl) from a bankrupt company (Pearl Automation) that works fine on my iPhone XS max running iOS 18 to my new iPhone 16 Pro Max. I used the iCloud mechanism to migrate to the iPhone 16. After the migration, the app's Icon shows up on the new phone with a download arrow, but the download fails because: "The app is no longer available in the App Store". Is there a work around?
