I'm having a problem logging into my telegraph account with safari browser, anyone else with a logging in problem?

I'm having a problem logging in to my Telegraph account using the Safari browser, I contacted the Telegraph media services and below is their response:

Thank you for contacting the Telegraph Media Group.

Further to your enquiry I am sorry to learn that you have encountered issues logging into your puzzles account.

I am sorry to advise that there appears to have been an update on the Safari browser which is preventing users logging in.

I can only suggest to use a different internet browser to access the puzzles until Safari are able to fix the issue with their browser.

I am sorry for any inconvenience caused.

The Problem started about a week ago, does anyone know if there was an automatic update in the last ten days or so and are there any others Safari users experiencing similar problems?
