Hello,

I have DisplayLink Manager 15.1.0 (Build 51) installed on my MacBook Pro M2 (13-inch) with macOS Tahoe 26.3.1. When I connect the Kensington SD4790P I click to allow the USB device to connect to the docking station. I have two of the same LG monitors connected to the docking station both via HDMI. Only one monitor will work not both with the display link software. When I open the DisplayLink software on the Displays tab it always says "After connecting accessory to this Mac via USB, a system prompt may appear. Please click "Allow" to ensure this device is working properly." I click allow every time I connect the Kensington docking station. Any ideas on what is the problem?
