Why is LinkedIn so slow?

Hi All

I run a MacBook Pro Retina with Sierra and having real problems over the past few weeks with linkedin.com.

Wherever I'm connected, LinkedIn is incredibly slow to refresh button clicks, in-field typing, searches - you name it, its all slow! Before you ask, I'm not experiencing similar issues with any recent website I've visited. Using different networks (fixed, wifi or mobile 3G/4G) makes no difference, so now unsure what the cause could be.

Wanted to check if anyone else is experiencing a similar problem, and can you offer any advice? Is it at their end? Thanks and look forward to hearing from folks!

Best regards

Andy
