I’m new to Shopify, still on the 3 day trial. I’ve tried completing the tutorial except one box won’t check, that’s the custom URL. I’m assuming that is changing the default random string of letters into an actual myshopify URL, which I had done first, now it will not check off. I’ve done everything in my power to make it check but nothing will work. I’m not too keen on pushing out 15$ just to complete a stupid tutorial. Any ideas how to fix this?
