Update the combined MFA/SSPR Registration's to not be dependent on 3rd-party cookies
Apple has enabled Prevent Cross-site Tracking by default in iOS 13.4. As noted in the article, users get a "Sorry, we can't sign you in" message when 3rd-party cookies are blocked. As a result, MFA/SSPR Registration is broken by default on iOS 13.4. A manual intervention is now required to allow 3rd-party cookies because the setting cannot be managed on a supervised device. Apple has provided prescriptive direction on how update apps. Please update the combined MFA/SSPR Registration's to not be dependent on 3rd-party cookies.
