I just checked and I’m seeing that also. It appears to have started immediately after the hub rebooted with the 0.30.4 beta firmware. (Android)
To be clear:
I checked a number of local and cloud devices. In the classic app, the Recently tab on the device is up to date with events. However, in the new app the History tab does not show any events since my hub was rebooted on Sunday at 12:15AM to get the firmware update. The values shown on devices in both apps agree; just the log of events is wrong in the new app. The events show up in the IDE.
Also, I have “All” selected for the Activity and Filters in the new app.
(Update: I reported this in centercode)
