Hey @Maury
Looking into this a little more.. The 2FA remember-me cookie set wasn't set as a session cookie but instead set to expire 2 days after the login.
I've raised itflow-org/itflow960 to (hopefully) correct this behaviour.
Once this is merged, please update and test again in a few days to see if this helps? In the dev console, you should then be able to see the cookie expiry date match your remember-me period (e.g. 60 days in the future).
