I’ve done some poking around, and I can’t find any resources on the topic – anyone know how to go about getting a published app listed in one of the app store collections? I’m particularly looking at the “Works with Online Store 2.0 themes” collection here: https://apps.shopify.com/collections/online-store-2 and I can only assume it’s some kind of manual curation process by Shopify staff?
Contacted support, got the answer: there is an App Review team, and the process for getting your app looked at is to manually reach out to support, who can forward your app to said Review team for evaluation on potential Collections it fits in to!
