Hey, found a solution!
So depending on where you got your domain, head to the settings.
Find something in advanced settings probably that says "A Record" and "CNAME Record"
For A Record, make sure it is set to 220.127.116.11
For CNAME Record, make sure it is set to shops.myshopify.com.
by the way, for the CNAME, make sure you even add that period in the end!
Hope this works for u!
