Shopify Network Admin ?

Hi Nanog, I am troubleshooting an issue where it appears that users orginitating from a certain subnet that I manage are unable to access websites hosted by Shopify. We have contacted Shopify support and are still waiting for resolution. If anybody here is from Shopify - I would like to get some guidance on how to proceed with the ticket so we can fix this issue for our mutual customers. Please contact me directly for additional information. Thank you, John
