Hi everyone! I encountered a peculiar issue today with my store.

Basically when I tap “add to cart” it brings me to website.com/cart but the cart is empty. That can happen multiple times until it finally works.

I am attaching a video.

(I was able to replicate and record the issue on a cheaper phone without a screen recording feature so had to film it with another phone)

It doesn’t show in the video but I tried with different products and I tried refreshing while in the cart.

I am not sure, but it’s like when I wait for the product page to load completely including the “Kupi odmah” (Buy Now) button that’s when the issue happens.

Store is on Serbian using Serbian RSD currency. The edits to the theme itself are minimal. I think that the only thing that was changed is that the reviews modal is above the bar at the bottom of the screen.

Installed apps:

I will try disabling some apps later to see if that fixes the issue and update. In the meantime, I would appreciate if anyone could share any knowledge about this.

Edit: uninstalled Yotpo Subscriptions and Kaktus - Preorder apps. The issue is still there.
Edit 2: Disabled Booster and MIDA Heatmap (not uninstalled), the issue persists.

Edit 3: Uploading all the changes I’ve made to the website that I was able to find.

This puts the Yotpo Reviews overlay when “Write a review” is pressed to be on top of everything.

This changes the font size of the letters of the navbar.

This adds social media icons to the header.

I think that these are the only changes I did to the theme.

Is the issue fixed now? because I went on your store and added a product to cart and it worked fine
