Guide data not showing in web UI or in app

I've just noticed this evening that guide data isn't showing either in the DVR Web UI or in app on Shield TV or Android Mobile, so nothing is scheduled to record even though I've got passes in place. I've tried restarting the server and re-downloading the guide data but to no avail.
DVR version is 2020.03.24.0127, Shield app version is Beta 103122. I've also just shared diagnostics for guide data.

Please refer to the official topic:
