Shopify DNS issue - transferred DNS to Shopify now email broken and store not working

Ticket number 29584178.
We transferred our DNS from Hover.com to Shopify and it broke our email and our store is still not visible - bigreuse.org. Gsuite email arriving sporadically.
Hover.com DNS was working fine for email at least even if redirect to Shopify was not working. Shopify DNS still pointing to our old Lightspeed store and broke our email.

I just read this on CloudFlare FAQ related to shopify issues. We had a Cloudflare account that we closed over a year ago. Cloudflare asks that Shopify tell them to remove all old registers if that is the issue.

Our email has been down for most of the day. Shopify DNS pointing to old Lightspeed store.
Shopify and Cloudflare have not help resolve the issue - even after I paid for new Cloudflare account. Shopify can’t even really tell me what issue is.

Anyone have any advice?

My exchange with Shopify support

(Support Advisor): We have an internal tool we are using that is spitting out this error message: “‘Domain is pointed to Shopify but did not return Shopify headers.’”

Justin: are the shopify dns records correct?

(Support Advisor): Yes, according to the specialist.

(Support Advisor): There’s another error in your internal admin page (only visible to us) that says “Shopify is not receiving requests on this domain”

(Support Advisor): The first error, “‘Domain is pointed to Shopify but did not return Shopify headers.’”, is under the section: Does it point to a Cloudflare proxy (unsupported)?

Still waiting for either Shopify to tell Cloudflare or for Cloudflare to remove legacy SSL Certificates. 3 days and counting. Cloudflare is saying they won’t remove SSL certificates from my domain unless Shopify tells them to - somehow legacy Cloudflare SSL certificates are Shopify’s responsibility to tell them to remove and verify. Shopify has told me I should try to get legacy SSL removed directly first despite Cloudflare saying they will only listen to Shopify. On Friday - we were told Shopify higher level tech team does not work weekends and will get back to me in 1-3 work days or maybe longer. A Shopify higher level tech with a very complete answer did get back to us on Sunday but has not responded since then - now Monday afternoon. I would be wary of using Shopify DNS in future - it should probably be left to DNS specialists.

Check your SSL Certificates at SSL Checker before moving your website.

I finally got Cloudflare to remove SSL legacy certs. They provided a TXT verfication code that I uploaded to Shopify DNS that allowed them to remove certificates after I signed up for paid Cloudflare account - I paid them to remove their services basically.
