Unable to Sync Devices

If you're unable to synchronize multiple devices, ensure that only one TRRS cable is used between devices. Connecting both the “Sync Out” and “Sync In” ports simultaneously using two cables will prevent proper synchronization. Verify that the cable is connected correctly, with “Sync Out” connected to “Sync In”, and avoid connecting multiple “Sync Out” ports together.

This should help restore synchronization between your devices.
