Update

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.
Alternatively, clients can use the link below, which downloads ISL Light and launches it directly in join mode:

Our team is actively working with Microsoft in order to get the false positive detections removed and the delay in administrative mode escalation removed.



We apologize for any inconvenience this may have caused and will continue to provide updates on the situation.
