We have been using the default Shopify integration with Facebook Pixel. it worked fine up until recently. We started getting critical warning from Facebook pixel manager that "Same Event ID Received for Many Event Instances". We believe this is causing conversion events to be duplicated across multiple ad sets, i.e. double-counting conversions!
Anyone has seen this recently? This error just came out of no where. We did not make any changes.
Thanks for bringing this up. We're investigating now, will post back here soon with an update.
Our teams have investigated and they've been unable to replicate the error. Can you confirm if you're still seeing this? If so please provide the shop_id and we can look further.
