**Update 2019-05-07: We are deprecating "Relevance score" from the connector, and have added the three replacement fields "Quality ranking", "Engagement rate ranking", and "Conversion rate ranking". So you can now replace the broken field with one or more of those. For more information on the new fields see this Facebook Business article. **
Facebook Ads API will be deprecating the following fields on April 30, 2019 in their UI interface and they will be removed in the v3.3 of the Marketing API:
- Offers saved
- Cost per offers saved
- Relevance score - replaced by "Quality ranking", "Engagement rate ranking", and "Conversion rate ranking"
- Messaging replies
- Cost per messaging reply
- Mobile App ROAS
- Web Purchase ROAS
We will mark the above items as (deprecated) in Supermetrics when we migrate to API version 3.3 later in the year (actual timeframe TBD). So the fields will not be removed immediately from Supermetrics, but you should plan ahead to remove or replace them in your reporting in preparation for their eventual removal.
Facebook has given replacement metrics to use instead, which are outlined in detail in this article - we will add the replacement metrics into our system if they do not exist already: https://www.facebook.com/business/help/1695754927158071?ref=FBB_MetricsUpdates
