Hey @ahawari,
Square plugin does not work with mobile customers. They cannot enter their card info. It is not clickable.
Looking at your site, the credit card fields for Square don’t appear to be working on mobile or desktop.
Looking at the browser console I can see a couple of errors relating to the Square extension: https://d.pr/i/Nagf3n
It looks like some files are not being loaded that are required for the extension to work properly. Often issues like this are caused by a conflict from another plugin or your theme. I would recommend performing a conflict test to confirm where the problem is coming from. We have a guide in our documentation that will walk you through the steps required for a conflict test: https://docs.woocommerce.com/document/how-to-test-for-conflicts/
Please let us know how you get on with that!
Kind regards,
