@buckyswider _matterc._udp is for commissioning, so that one is only present while the device is "pairable", typically 15 minutes after boot when the device is factory reset (i.e. no Matter pairings yet).
_matter._tcp shall be advertised after the device has been commissioned (paired), one service per "fabric" (i.e. per "hub" it has been commissioned to), as long as it is powered on and connected to the network. If it does not advertise this service, it will not be possible to reach it by Matter controllers. If you don't see this service when you expect to, it seems like a bug in that device.
Maybe you have devices from other Matter brands you can test with?
