Badge icon not showing up at first

I’m using Drafts in macOS, iOS, iPadOS and WatchOS. Latest versions on each. The badge icon shows the number of items in my Inbox on everything but the Mac. But … after I click on the Drafts icon in my dock, then the badge shows the number of items in my inbox.

I have allowed Notifications for Drafts in settings. And in Drafts settings I’ve clicked Launch at Login. Not sure why it’s holding back the badge until I click on the app.

Any ideas?
