Unable to cache

Hello!
I started to see a message in Swift Performance’s Dashboard after I updated it to the 2.0.7 version, and now I’m unable to pre-cache my pages. The message says: “Your session has expired. Please refresh the page and try again.”
I’d appreciate any sort of info that would lead to solving this issue, as my loading speed and bounce rate are going up since this problem occurred.
Thanks in advance!
