We have an iOS app that connect to Azure AD for authentication. We use MSAL library in iOS app to call the azure AD. We are facing some issue when trying to authenticate. The error says that we need to configure the app registration to support multi tenant application. The error is confusing because we only have one tenant in our Azure AD.

If we add the tenant it will ask for Approval. Why it's asking for approval? how can we remove that approval?
