Due to COVID-19's impact on physical store locations, Facebook has made some adjustments to how the Store Traffic Ads behave and the functionality available.
Most of these do not impact Supermetrics for Facebook Ads connector, but the changes to only allow Store Traffic ads to run in the "Facebook News Feed" placement could cause some confusion, especially if the ads had been set to other placements before.
Per the guidelines:
If you restart an [Store Traffic] ad campaign that was paused, it will only appear on Facebook News Feed right now, not any other placements it was previously running on. If you selected more placements when you created your campaign, your ads will start delivering on those placements as soon as they become available.
