Hi all
In my Cloud instance, I am trying to @mention a specific user in an automation action using the smart value instructions outlined here.
So I went to my profile as instructed and took the last part of the URL as below

to use in the format [~accountId:7120...a8f] which resulted in this:

I note that in my URL there is a % rather than a : as per the Atlassian instructions. Out of interest I replaced this but that didn't work.
Does anybody have any idea what I'm doing wrong, please?
I managed to do this easily in Server but have just moved over to Cloud and trying to re-create all my existing automations.
Thanks heaps, Brendan
