We have a mobile app (iOS specifically) and we want to display a popup to our users when our Terms and Conditions or Privacy Policy changes and explicitly require them to accept or reject the new terms.
If the user rejects the terms of the privacy policy they should be unable to continue to use the app. How should we handle this experience?
Obviously, we want the users to be able to reaccept the policy if they accidentally clicked the wrong button. So far the best solution I have been able to come up with is to display an alert if the user rejects informing them that they cannot use the app until the accept. Every time they come back to the app, they will be prompted to accept the new policy.
