I have issues connecting 2 ZWO Cameras to Ekos with the latest version. I'm using a Asi533MCPro for imaging and an ASI 120mini for guiding, most of the time with PhD but sometimes using the internat guider.
In the previous version that I used (3.6.5) everything was connecting fine. In the image train I had to set ZWO camera 1 (imaging) or ZWO camera 2 (guider).
In the latest version I can only choose ZWO camera and only the 120mini appears.
An additional test with an StarlightXPress Lodestar leads to the same result, the 533 is not connecting.
