Thanks for the answer.
I logged into my account and clicked video call link in my dashboard page.
But it goes to home page of help center. And it displays as I did not logged in, although I logged in.
Yes, I tried what you said.
I refresh help center page and clicked login button, then it goes to my upwork home page.
Url is weird.
Even when I am going to visit Help and Support Page by clicking Help and Support under question mark menu, it redirects to https://www.upwork.com/ab/find-work/?kind=error&message=Invalid%20data%20from%20remote%20sign-in%20m....
I appreciate if you fix this problem for me.
Could you please try accessing the Help Center page again and let me know if you're able to see and use the button as explained in the notification?
