Shopify does not track my visits from united kingdom

Hi,
We’ve being having big issues with our shopify store.
We have a brand that only sells in UK, and Shopify does not track any visits from this countries (and it doesn’t track add to carts, initiate checkout, purchase…)

We really don’t know what the issues is.

2 months ago with didn’t have this problem, we managed to have UK visits tracked on our shopify store.
Here’s our website : https://www.trycharmant.com
Did someone had something similar and knows how to fix it?

Thanks a lot in advance.
