I have my website (www.kavipoetryart.in) in Prestige theme. Today, suddenly my checkout stopped working. Customers are not able to go beyond the cart page. Customers aren't getting any error message but the cart page is refreshing when clicking on check out button. I hadn't made any recent changes from the backend. There was one app (https://apps.shopify.com/whatsapp-chat-api) which asked for update and I did.
Few days back I had similar problem when I installed Google Tag Manager to the website. However, when I removed it, it was working well.
Could you please help me in resolving the problem? Thanks in advance.
