Here's a decent write up.

In short, 3rd-party cookies and storage are being blocked (or phased out). This means you can insert an iframe into a page but the cookies/storage it has access to will be partitioned based on the origin of the top-level context.

E.g. If PayPal embeds an iframe in walmart.com's site and the user logs in to PayPal to pay then goes to target.com's site where there is also an iframe embedded the user will have no active session and will need to login again.
