Confused About PayPal's 30 June Emails?

If you are like the majority of the world you probably use Chrome as you web browser and you have kept it up to date.  In fact you have verified you are running the latest version.  Yet despite this you keep being warned by PayPal when you login PayPal or, maybe you even got that ominous email saying you need to upgrade your browser “to continue accessing”
So what is the story? Is Chrome not compliant? Is that likely?  I don’t think so. It just seems to be so much easier for PayPal to send out emails regardless.

If it says “PayPal_Connection_OK”.  If not then update your browser.  How many times do they have to ask?
Roll on 30 June so these annoying messages can stop.
