I cannot create a message in Inbox > Support.... Can you?
One way to contact the support is through Extranet > Inbox > Support.
It says so here: https://partner.booking.com/en-us/help/support-contact/how-do-i-contact…
However, There I cannot create a new message. What am I missing?
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.
Reminder you cannot post actions requests or any action request on here.
