Yahoo Mail Access From Chrome

[Fenderblender]

Just recently my access to my Sky mail on Yahoo has stopped working with the following message on a blank page

{"message":"Control character in cookie value or attribute."}  

 I'm using windows 11 Pro and the very latest Chrome browser and I can access the mail if I use Firefox instead buit my preference for browsing is Chrome which has suddenly stopped working for this site. It also blocks access to this forum from the Sky Help page or main account when signed in?

Delete your cookies in Chrome.

Close all Sky websites, and then clear your browser cache (cookies, history etc). That will resolve it.
