This is embarrassing,  what the hell Shopify is doing.  This shouldn't be rocket science to do.  At least acknowledging the issue or making a statement about it... is not rocket science.

thanks for the reply.  I am not sure what you mean by product ''ID''. I tested 5 products and they all had the same issue.  However, I change my browser from Firefox to Edge and it was all good.  The issue must be coming from the Firefox browser.   D...

I am getting the error: ''Required parameter missing or invalid:id''  when adding a product to the cart.  I search for a solution but have yet to find a solution.  Can anyone help, please?thanks
