I've seen the email about third party cookies and safari blocking cross tracking. But it seems by reading the webkit blog it says that session cookies are ok and persistent cookies with a less than 7 day expiration time are ok too.
Am I understanding correctly?
Or do you have to completely get rid of persistent cookies and use the local storage?
Apple has announced Intelligent Tracking Prevention (ITP) 2.1 with Safari version 12.1+. This means that your embedded app may no longer work for merchants attempting to access it using this new version of Safari.
