With such unclear messages or issue descriptions one does not understand what the purpose of those opened issues is.

The title of that issue is update Send, so it is not clear to me if it is about the send workflow documentation, or the pictures or the privacy warnings, or all those together.

Make sure to describe your comments and issues to avoid any confusion for others.

If you didn't understand my message above read it again, or ask me to clarify it for you.
Otherwise this non sense ? do not help us move forward and just waste others time.
