Sometimes it is there. Sometimes not. Your Answer-Woman on CHAT said "it appears at random on the tool bar."
I think it is such a good idea that it should ALWAYS appear there so we poor ignorant customers don't have to be looking around for it -- and don't have to just wander off when we don't find it.
This is not MY idea, but YOURS. I just think it is such a good idea it should be there immediately after we punch in a future date and time to publish our campaigns.
AND I think it is a great idea that you allow us to gripe and moan at you like this.
