I have never tried to write an article on the app. But I will tell you about a similar problem on the app. I have never been able to find a private note on the app. The private notes are visible only on the PC. My e-mail would notify that a private note has been added to my article. When I check the e-mail, I read only the first two lines of the note. When I click on the view note, it is not there on the app. Every time I have to log in to my PC to read those notes.
