"TimeOut" when I want to connect two cameras

Hi,

I have issues when connecting two cameras at once on manycam, telling me “TimeOut”.

Both cameras works fine individually whenever I use on Zoom, FaceTime and even ManyCam. So this is not a “incompatible” issue. It always happens when I want to connect two cameras at once.

I have a Raze Kiyo and Depstech Webcam.

Any solutions ? I must use two cameras for my work.

Thank you.
