Please check your Billing summary, your payment should be there (if you paid by money transfer it could take up to 5 days to process)
Also consider, Video Ads needs a few hour (a day) to populate the system.
Then check date range (if it is a recent ad, you should include “today” as well) for your reports.
If your date range is correct, then check:
the size of your audience, if it is too small your ads will not be shown (gender, age, remarketing list size etc.)Your device settings (desktop, mobile, TV)location targeting – should be large enough.placements – if you set managed placements only, and provided only a few placement, that could prevent displaying you ads.all bid modifiers (could be device, audience, location)your daily budget (for example if you use target CPA, your budget should be at least 5-10 times higher than the target CPA)your bidding (depends on campaign type – max. CPV, Target CPA etc, is high enough?)
