Duplicate events Shopify FB CAPI

As freelancer being active on Upwork, I noticed many Shopify store owners complaining about duplicate conversions in FB Ads stats compared with Shopify stats.

Currently I have a Shopify customer dealing with the same, Is anyone experiencing the same?

@Michel_Brok an important piece of context here would be how their FB is set up? Native FB app? sGTM? something else? :slight_smile:

Happy to look into this but need much more input
