Do you have an example of using App Group to share data? My DeviceActivityMonitor extension is firing the intervalDidStart(), but the categoryTokens in stored in the shared model are empty when it fires. However, when I run it using a button action in the foreground, the categoryTokens are founded and successfully shielded.
I tried adding App Group capability to the main app target, and the DeviceActivityMonitorExtension target. Any insight would be appreciated.
