I tried to transfer my store's domain to the Shopify one but it kept giving me errors like "this domain is taken" or "invalid site address". I tried all the different combos and nothing successfully changed.
Now, when I go to my domain it says "Sorry! This site is currently unavailable! Come Back Soon" from Shopify. At the bottom I can contact support but they've made it difficult to talk to a human with reduced staff and such.
