The issue with administrative mode escalation has been identified to be caused by Microsoft Defender. Disabling Microsoft Defender or adding appropriate exclusions on the remote device removes the problematic delay.


As a temporary solution, we recommend that users advise their clients to utilize ISL Light's join mode when entering a session via a session code.
