will this plugin be compatible with the woocommerce 3.o major update? Thanks

Hello,

My website https://www.adunniorganics.com uses your excellent plugin which has been most useful. A few days ago, I noticed that the states drop down is missing when customers try to buy from their mobile phones. I’m not a developer, I just built my site as a challenge to myself, so it could be a minor problem, nd I’m sorry if this is a silly question. Please help!
