We have the Palo Alto Theme and sometimes the drop downs are not working. Our site is greenwayscc.com and when you click on a product and select the size, the size might not change at times. Also sometimes it states out of stock and when you refresh the site it states in stock.
We did contact them and they are looking into it, but they are so slow to fix issues and respond sometimes. It seems like contact person is not developer and he forwards messages. They have been better lately, but he also stated it might be an app we have in our store but I beleive this is not the case. We did not install new apps and after update had issues. I cannot put blame on them, but I wish theme support had quicker customer service. I wish there were themes with direct phone contact.
