Same Day Post
I attempted my first Post today and it is for an event taking place later today. When I attempted to preview the post, I am told I cannot post an event that has already taken place. But it hasn't yet taken place (it will take place 5 hours from the time I am attempting to post).
It seems we can post events not for the same day. Have to do this a day in advance at the least.
