Coding solution for unsupported integration

Site URL: https://www.klaraprosova.com/virtual-boutique-2#!/all

Would anyone be able to help me with making an unsupported integration work properly in my Squarespace site please?

I have integrated my Spreadshop site into Squarespace site by injecting a code to the page. Browsing the shop works great, but the shop is set up as multilingual and is supposed to change/offer you to change country, which would change language, measurements and currency, but that is not happening. Currently everyone sees what applies for GB and there is no possibility to switch.

Spreadshop support says it's likely some error with the integration. 

Is that solvable and how?

Thank you in advance,

Klara

Hi,

Can you paste all embed code here?

Hi, I believe I can, here it is. The site is set up as multilingual site at Spreadshop, but on my website, only the GB version shows. So perhaps something around that part needs to change.

Thank you.
