TravelPixel and chrisuk - is this still happening for you? There are two possibilities I can think of here. One- we had some ad delivery issues over the weekend which should have been resolved as of Sunday morning Dec. 3.

Another option - do you have your budget set to "Divide budget across the month"? We recently implemented a change to this feature so that it more accurately predicts how many impressions your ad should receive to best use your budget. So in some cases, you won’t always see your ad because it is being spread evenly across the month in order to minimize the chance of the budget depleting prematurely.

Please let me know what you think - I'd like to help you get this resolved.

Thanks,
