After update to macOS 13.4, DL Manager 1.8.1 no longer mirroring diplays using DL t.
 

I just updated my Macbook to MacOS 13.4 and I can no longer get the Logitech Swytch + Rally Bar to Mirror Display on the Front of Room Display.

I was running several tests during the course of the day and with MacOS 13.3.1 I was able to use the Swytch which uses DisplayLink technology to mirror displays using Logitech Swytch + Rally Bar.

Immediately after the update this stopped and the Rally Bar no longer detects the incoming display from the Macbook.

Will open a ticket but I see several posts about macOS 13.4 breaking DL Manager 1.8.1
