Interesting that the projected Matter platform change (referenced in the linked article above) also leaves out 1st gen Alexa devices. But as far as I can tell, those devices’ Plex problem is directly related to the Let’s Encrypt expired certificate that has affected other software around the world. This includes the Plex for TiVo software (which has a workaround of setting it to not require a secured connection on local devices).
