Mail displaying text but links no longer work in emails?

Mail no longer shows any working links in emails, all working fine untill a few days ago.

Now wen I get an email with a link to a website it is no longer underlined so can't click it to bring me to the page.

Same is also thrue for my iPhone as well as iPad.

My google account is not affected and works fine.

Any ideas? Has Apple turned it off?
