Google Nest Community

By the way, it's not an issue external to the Home app. Siri brings up all of those stations.

Just adding that neither of my two Google minis, nor a JBL portable speaker will play any radio station via any service (e.g. Audacity or iHeart radio). For example, WXRT in Chicago, WTMJ in Milwaukee, WUWM in Milwaukee, WBEZ in Chicago.
