Hi everyone,
I’m aware of this issue and have been working on it for a while now.
Apple changed something with the App Store receipts in macOS 26.4, and I’m still trying to figure out exactly what. The tricky part is that everything works perfectly when testing through TestFlight, but breaks after the app goes live on the App Store. That makes it really hard to debug.
I’m reaching out to Apple’s developer support for help, so hopefully I’ll have more clarity soon.
I’m really sorry for the trouble this is causing. I appreciate your patience while I get this sorted out.
