Has something changed in 2.2x? Because before, they would only know that their post was not showing if they were viewing as a guest. Now it seems (because of the number of dup posts and a few saying their post just disappeared) that the posts awaiting moderation are disappearing while they are still logged in.
I never had this issue before when I wrapped the awaiting message in a conditional to only show to admins and mods.
Not long. from a few minutes to an hr. I'm going to test this again but as soon as you navigate to another page, then back to the thread you posted in, it's gone.
