Hi,
About 2 weeks ago I had to re-install with a fresh copy of Raspbian Stretch and noticed both the Calendar and weather wasn’t working. The default weather module displays nothing at all although its enabled and APIs are set and the calendar shows “No upcoming events…” no matter what URL or ical file I use. My calendars display fine on other apps/devices so it just seems like its not pulling the data or something although its there. @sdetweil and @Sean I’m not sure if you guys are the developers but I see you were in another post troubleshooting so if not, please forgive me!
