Flex issues with Chrome 80.0.3987.132?

Is anyone else having issues with yesterday's (March 3, 2020) Chrome release and Flash applications? We are getting customer reports of two problems... users being kicked out of the application, and users getting an error message, "Detected duplicate HTTP-based FlexSessions, generally due to the remote host disabling session cookies. Session cookies must be enabled to manage the client connection correctly."

We have replaced Flash with HTML5 with later versions of our application, but we still have users on the Flash version that we need to support a bit longer. Chrome release notes say that there were 4 security fixes, but I don't have access to any details.

Has anyone else encountered problems with this release? Figured out what the issue is? Or how to resolve it? 

Thanks
