Based on the announcement here, I created Home page ads set to specific Merchant plans. Over the last 10 days, these ads have had zero impressions.
Support suggested that my apps are just not getting engagement but its not an engagement issue, the impressions were zero on those ads.
To test whether the issue was related to merchant specific plans, I created a new home page ad with the exact same budget and bid limit, without limiting it to a specific merchant plan, and the ad instantly got impressions.
Anyone else see this issue?
