Red's Fly Shop review for Google & YouTube

My goal was connecting YouTube shopping as our videos are the #1 source of conversion. This App is extremely frustrating. Forced me to create a new Merchant Center account rather than feed to our existing account which has worked perfectly for years. This shut down my Google Ad campaigns for a week while waiting for approval of products and various errors to patch up. Finally all connected, new Merchant Center is up and running. STILL CANNOT GET YOUTUBE TO PICKUP OUR PRODUCTS! I lost a significant amount of revenue in this transition, and it seems like Shopify isn't providing any support. There should be a litany of troubleshooting videos. Very disappointed.
