You must wait until the approval goes through, give it a minute or two. If the interface seems to be stuck, simply refresh the page and repeat the steps we followed thus far. Once you get to the latest step, you shouldn't have to "Approve Transfer" (1.) anymore. Instead you will see the "Start Transfer" (2.) dialog and button, which you should go ahead and press! In the final step, you are just waiting for your funds to be delivered on the Cronos network (3.)! Done!
