The issue has nothing to do with the cache of the mobile phone. We have tested on several phones and tablets and the issue is the same.
Yes, you can click the dropdown menu but the jewelry displayed in each cathegory is not displayed correctly and you cannot use/click on the secondary cathegories.
Please compare the desktop version and the mobile/tablet version.
This is an extremely important issue for us, since over 60% of our customers use their phones to order items from or shop - and we noticed a significand drop in sales since we updated X theme and Cornerstone.
Thank you.
