I am as well having the same issue of SSL pending.
My domain snapretail.com.au is registered with Crazy Domain. I have checked with Crazy Doamin team and they confirmed the below
A Record Pointing to 220.127.116.11 and there is only one A record
CNAME Pointing to shops.shopify.com and there is only one CNAME
No AAAA record
No CAA Record
Even after 48 hours the SSL is penidng.
Can you please check?
Ted here from Shopify, thanks for letting us know.
I've gone ahead and pushed through those SSL certs again and everything is up and running now. I can see that you are still setting up your store.
If there is anything else I can help you with, please let me know, I'm happy to help!
