Event ticket price setup is a problem. Even in your demo site, you set the price for "Linkin Park" in backend set as 55 euros. However, the seats prices are different for example, closure seats are 55 and back seats should be less. However, if you go to frontend then no matter whichever seat you choose they are all for 55 euros. Also, even if you select more than 1 seats and go to your cart, it only adds 1 seat.
In my second test, I tried selecting 3 seats but it only added 2 seats.
Also, there is no option to set "Delivery Prices". It takes product prices only. Which is also not get added to the cart.
Can you please help me with this?
