Issues with Herelink video switching

Hello,

I’m using 2 Herelink Air Units on a drone to stream the FPV and gimbal camera feed in the following way:

The 1st AU is streaming both the FPV feed and the Gimbal camera feed to the pilot’s Herelink GCS.

The 2nd AU is streaming just the Gimbal camera feed to the 2nd Herelink GCS.

I also have an HDMI Splitter 1 in 2 Out that splits the Gimbal camera feed to the pilot’s and 2nd Herelink GCS.

Everything works fine when I power up the system. The problem is that when I switch feeds from the pilot’s Herelink all video feeds freeze in both controllers.

Do you might know what is causing this issue? All AU and TXs are updated to the latest stable firmware.
