Hi Team,
We’re encountering a device-specific issue with our SMS Message Filter extension. The extension works as expected on an iPhone 11 running iOS 16.6, but it does not trigger on an iPhone 12 Pro running iOS 16.7.
Key Observations:
- The extension is implemented using ILMessageFilterExtension and calls
messageFilterOffline(appGroupIdentifier:for:)from our shared library. - The App Group is properly configured and accessible across the app and extension.
- The extension is enabled under Settings > Messages > Unknown & Spam.
- There are no crashes or error logs reported on the affected device.
- The issue is consistently reproducible — it works on one device but not the other.
We’re wondering if this could be a regression or a device-specific behavior change introduced in iOS 16.7.
Has anyone encountered similar inconsistencies in Message Filter extensions across different iOS versions or device models?
Any guidance or suggestions would be greatly appreciated.
Thanks in advance!
