Hi, Our application is a B2B app, supporting users from companies that own our equipment (print industry). We want to allow company stakeholders to have a "Premium Plan" that will provide their company with numerous advantages in different aspects (service, training, data visibility) Some features in our app will be locked/hidden if the company is not part of the Premium Plan. We want to allow authorized users to activate the Premium plan for their entire company. We already have our website, where we already have a marketplace that allows web users to do this (using their company service agreement). In term of complying with Apple's in-app purchase Policy, is it ok to tell users in the app to go to this marketplace if they want these features (and more)? Thank you
