When opening our App Clip from a Live Activity, the iOS system Handoff alert blocks our app on open. It is reproducible 100% of the time. The description in the system alert is: Waiting for Handoff to {My App}. We never had this issue before and believe it is related to iOS 18. I don't have Handoff enabled anywhere in my app.
All uses of NSUserActivity explicitly block handoff
userActivity.isEligibleForHandoff = false
We have been able to locate this same issue in other iOS apps that use Live Activities and App Clips. Is this an iOS 18 system-level bug?
