I second this. 2 updates ago I got a repair warning stating my Zigbee and Matter were using different channels. During that time I noticed delays with my devices. As soon as I put them on the same channel I noticed an immediate improvement. But I am using Skyconnect as multi-protocol so this may differ from OPs setup.
