No inbox count on dock icon

I’ve selected Dock icon Badge in preferences, but I do not get any inbox count on my dock icon.

Same is also true on my iPhone. Am I doing something wrong?

The first time you enabled that switch, you should have been asked to grant notification permissions. If you did not allow them, they badge will not appear. Check in iOS Settings > Notifications that you have allowed Drafts permissions to display badges.

Oddly, Drafts does not show as a listed app under Notifications. Should I just delete the app and re-install?
