Is it possible that you’re using a canary version of Chrome? Check chrome://version/, for me I see version 69 and I can go to https://www.paypal.com/ and see that the Symantec EV cert is still valid, which was issued in 2017. In particular, if you see version 70, I would expect you to get errors visiting PayPal, just like the roadmap says.

Personally I think it’s bad practice to have a cert last more than a year in the first place, due to a number of both operational concerns and security concerns, but that is neither here nor there.
