If you move away from Shopify then it may well be this, unfortunately a common problem that Shopify themselves should be aware of and let you know about.
I am having a lot of trouble getting Cloudflare Support to actually ASSIST with my issue. They keep rejecting and sending me to the Cloudflare Community, even with my latest submission containing all of these details and it certainly seems like only Cloudflare Support can FIX the issue. I am not sure what else I can do?
Thank you, sorry I DID actually try that link and I thought it was broken because the submit button didn’t do anything. I realize now I didn’t enter the hostname in the correct format (no https://). I will try this out now!
