Known issues with the Mac App Store that may occur when installing an app purchased on an iOS device to a Mac.

For apps that are compatible with both iOS and macOS, if you have already purchased the app on your iOS device, you should be able to download it for free as long as you use the same Apple ID on macOS as on your iOS device.

Unfortunately, the Mac App Store is known to have a display bug regarding apps already purchased on an iOS device. In this case, you should still be able to continue the purchase process and eventually download the app for free.

This issue can occur with any app for both iOS and macOS. The same problem can occur in any developer's app. This is an App Store issue and as a developer I am not competent to resolve issues that occur within the App Store.
