VSI: Variants Shared Inventory

This app worked quite well for us for several months. However, it suddenly started to really bog down our website causing add to cart buttons to load very slowly - sometimes taking over 2 minutes for the add to cart button to appear on product pages. On some of our product pages, the add to cart button would not appear at all. After updating our theme, deleting unused apps, and other general cleanup, I eventually decided to uninstall this app. Once I did - the problems resolved immediately. I really wanted this to work for us as the shared inventory function DID work beautifully. However, its hardly worth it when we're losing sales because potential customers cannot add items to their carts.

its not really what i want especially when it want me to turn off track inventory functions, that all the point of sales are not able to check the quantity of the stock

App needs full acces to all customer data like IP address and Geolocation, which seems strange to me. Also, no clue how this should work, the guide is very incomplete and I couldn't get it to work
