I cannot create a message in Inbox > Support.... Can you?

Yes I have had words with them over the wording on that page and even the latest revision is still terrible , that is why I have created my own guide... 

and I snip and include it as my signature below when I reply to most.

see below.

Reminder you cannot post actions requests or any action request on here.
