Kissan International review for Shop

I set up app but it's not loading or letting me manage my products in the sales channel. "No products found" in All/approved/not approved. It says in Products - "You don’t have any products yet." but when I hit "manage products" It's says all have been enabled. It's been a couple of hours so surely this should populate by now. Also lastly, there is no easy help option to contact the app for how to rectify.
