i have custom app and i am using wix ecom api. i am only working with order related api. but on my app dashboard i got message like **All new sites with Wix Stores will soon be using Catalog V3 APIs. To ensure that your app is compatible with new and existing sites, add support for both catalogv1 and v3.** but i have only implemented ecom api. can i submit my app directly or what do i need to do?
