Notes disappear when touching elsewhere on document

I am using Acrobat Reader 21.05.00 (20210519.165138) on an iPad and when I am writing a sticky note this disappears if I accidentally touch elsewhere on the document. It does not matter whether I am typing or handwriting the note. There should be a notice given to the user to Post or disregard the note when (often accidentally) she changes the focus outside the sticky note.
