Hey, I just discovered this problem in case someone else is searching around for the solution.
If you are using Shopify’s native bundle functionality (a product that exists which is a bundle of two other existing products) - and you set an automation for that to sync to Shopify on purchase… the order will not pull through.
So if you’ve been having intermittent issues with Shopify orders coming through this may be the root cause.
@anwerashif is this a known issue?
