The previous issue was closed without a solution. I get this message, no matter how recent my _u cookie is even though i have access to the new bing. Any solutions?

I published an earlier issue, and in my case, there was a typo in the cookie value. Try copying and modifying the _U value again.

Modifying the _U value? I just copy pasted it and it didn't work

Same issue here. Maybe Bing finally locked things down on their end.

you need KievRPSSecAuth in addition to _U, separate the two key-value pairs with a semicolon, like: KievRPSSecAuth=stuff;_U=stuff

I have all the required cookies in my .json but I still get the conversationSignature error. Can you please help me out?
