You are soooo cool！Thanks you so much！Follow your steps and I solve this problem， by the way do you know how to solve the same problem with ins?
Instagram Shopping isn’t available for your account due to the following reasons:
Here's how you can find your commerce manager...
1- Go to your business manager.
2- Click on 'business settings' (a gear icon!)
3- Under 'Accounts' section, you can find your commerce account.
NOTE: For solving the FB shop issue, you don't need to find your commerce account, if you will follow the steps, your commerce account will automatically be created.
It worked out. Thanks for your help. I have only one concern can we use this shop & catalog for dynamic ads. Moreover, now I can see 2 catalogs in my account. One says Products from Shopify Store URL and other Shopify product catalogs. What should we do with these?
