We have been improving Google Shopping Feeds for our clients with Google FeedGen & Producthero Products AI. However, when it was time to add our new supplemental feed to Merchant Center Next, I realized that I could not add a supplemental feed anymore since migrating to Merchant Center next.
3 steps to adding Supplemental Feeds in Merchant Center Next
1.Go to Settings > Add ons
2. Add the add on: Advanced Data Soure Management
3. Add Supplemental Feed via Datasources > Supplemtal Feeds
