I just updated to Big Sur; I liked having the widget, but now it seems to be gone? Am I missing something, or are macOS widgets gone?
They are there. Maybe just a temporary issue with registration of the extension at the system level. Try a reboot yet? Possible re-install Drafts?
Unfortunately, no luck with either solution; it’s still missing. No big deal! I only used the feature once or twice, so no significant loss.
The widget came back after the most recent update; I guess that process cleared out whatever cruft was causing the problem.
