No, not necessarily.
When the crohn runs which is 11 am central time zone (my time zone), new ads
are automatically entered. With that said, just because they are on auto pilot,
does not necessarily mean they are going to run at exactly 11 on the dot.
In regards to what you're experiencing, if you click around the next day, eventually
you should see them. I've gone two or more days at times recently without clicking
and then when I go to click, it seems never ending.
In other words, those standard 1/4 cent ads are probably still going to be there later
in the day.
