I recently purchased PVT and ran into a serious problem with it and WooCommerce Min/Max Quantities capabilities. https://woocommerce.com/products/minmax-quantities/?quid=eabb618ae2d1856af7d0be148c93d5c4
Since this is a standard WooCommerce plugin which enforces a minimum / maximum quantity selection of an item when being added to the cart, I was assuming this would have worked.
Unfortunately, the page crashes with a fatal error: Uncaught Error: Call to a member function get_id() on string ….
I have a screenshot if a dev would like me to email it.
