The products cannot be added to the cart.

Hello!

I need help because, from the mobile version (it works correctly on the computer), the products cannot be added to the cart. Even when choosing and selecting the respective options, an error pops up saying, “Please choose the product options by visiting …x.” I don’t understand why this might be happening. I use the YITH Product Add-ons & Extra Options plugin for this feature. It is updated, and I have tried deactivating and reactivating it. Does anyone know what might be happening? Thank you very much.
