Duplication of the posts on WordPress shared from the same note (iPad)

Testing version:

What were you doing:
Publishing (exporting) from iPad to WordPress.com.

What feature did you use:
Exporting the post via WordPress application.

What happened:
A new post from singular note is published every time I amend the note and share it

What did you expect to happen:
The same post get updated every time I update and share the note the post was created from.

Is something in Wordpress needs to be setup first, perhaps?

Yes, this sounds like some preference in the Wordpress app or its extension.
