Do we need to include a way for users to disable push notifications in-app after agreeing to push notifications? Thank you!

If our app creates personalized content for a user using data that the user willfully gives, as per Apple guidelines, must the user be able to opt out of receiving the content? Thank you so much!

Hi! The app that I am building has the ability for users to join and be added to groups. Are there any requirements from Apple beyond the ability to leave and report the group that the user must be able to do? I read through the developer guidelines but I just wanted to make sure before submission. Thank you!
