Premium app features on iPad not available on iPhone
I purchased an app on my iPad. Beginner level. I shows up on iPhone but only parts of it work. I paid for premium level on iPad, but some features are still locked out on iPhone. Both use same Apple account. Both iOS 26.3.
Developer can't help. Apple Tech can't help. I went to phone settings and turned on all the Automatic Downloads features. Any suggestions? Should I name the app for this discussion?
The developer says the iPhone app is unable to send or receive data from App Store which means I have an amount or setting wrong. I've never had this problem with other apps.
