There are several reasons why you might not be seeing ad data or metrics:

1. The announcement has just gone live and there are no metrics available yet due to a slight delay. These delays are normal.

2. The date range you are viewing corresponds to a period in which the ad was not in circulation. Learn how to update the date range of data that appears in Meta Ads Manager.

3. The ad was not approved. Review the reasons for rejection of the advertisement.

4. You made changes to the ad. Wait a bit and check the metrics again. Ads or results may not display immediately.
