Hi, recently I've been doing a research in guidelines about how important is to create a "Register your interest" page on a IOS app for the app store, in order to check if it is relevant or a must have thing.Unfortunely I haven't found anything related with that on guidelines or maybe I've missed it, do you know guys something about this? Is it a good practice? does it help in order to be well ranked on app store?Thanks for the support 🙂.
