Opening today's daily note creates duplicate

Happens every time. Each open daily note action creates an extra dupe.

This was happening because my custom daily note format had an extra forward slash. On reviving this the problem disappeared.

Replaced: YYYY/YYYY-MM//YYYY-MM-DD

With: YYYY/YYYY-MM/YYYY-MM-DD

Hope that helps.

That’s custom daily note format, and an extra forward slash.

Can’t see how to edit post on mobile.

Could you post the solution to the problem in a comment so it can be marked as the solution?

I edited the post for you. New users can’t edit (it’s a spam prevention measure). You’ll be able to edit after a little while of being active.
