How to fix error "Session fixation mismatch" when using SSO ? 
Question

Hi All,
I have a problem with Single Sign On on some scenarios with multiple frontends or reload page when session expires. This lead to "Session fixation mismatch" errors.That error happens occasionally.Is there any solution that resolves this case completely?
(My version outsystem : 11.0.211.0)
Thanks you.
