v18 - BUG: unable to login to webconsole from within Sophos central since latest update

Question

Hi together, 
 I am experiencing another annoying bug regarding v18 and Sophos Central. 
 Since the latest release SFOS 18.0.1 MR-1-Build396 I am unable to access the webconsole of firewalls once they are in full sync with my configured Sophos central policies. 
 When I try to access the device through Central, not the appliance dashboard but its login screen appears. Logging in with valid credentials will at first show the login disclaimer page that I enabled on all appliances but after clicking "accept" the login page is shown again. 
 This issue did definitely not exist in any previous v18 build.

Is this a known issue? 
 Kind regards, 
 David

This is kinda a rare issue in which the the session of Central was existing but timed out and central, instead of login in again, does not pickup the old session and instead through the webadmin. 
 Do you have any log off Webadmin configuration or something special in place? 
 Can you reproduce this after some time? (So maybe tomorrow, still this issue?). 
 Is this a HA Appliance?
