Help- customers can't get past Shipping in check out!

Site URL: https://www.wrklfe.com/

I just did a soft launch on my store and now I am getting contacted by customers that they can't get past the address form in my checkout. Once an address is inputed there is no way to continue! 

Can anyone help?
 

Hi kbowman16, I'm having this problem right now. Can you share with me the fix that Squarespace shared with you please? 

@RestAngles There may be an issue currently. See:

Hello! I'm also having this problem right now. Could you please share the solution they shared? Thank you!

UPDATE:

I believe I found a solution that may be helpful! On my site, my shipping options were all calculated. However, I am not paying for the version of Squarespace that allows calculated shipping rates. Hence, none of them showed up at checkout, and my customers could not continue past shipping (because they could not choose a delivery option.) I went into Shipping settings, changed all my rates to a flat rate, and added the prices manually, and they all showed up at checkout.

Now the continue button is visible, and my customers can move on to the next step in the checkout process. 

I hope this helps anyone who has the same problem!
