I have to echo.    Most smart speakers connect via a site like Tune-In.   Tune-In sometimes does not update their info with the new brand name, or call letters.   There is ways around this on the station end by alerting these sites early OR keeping the stream url the same should the station move to a different studio/frequency home.   Stations also should ensure to update their streaming meta data when changes happen.   Sadly to often engineering forgets to do this for a while, which delays the update on sites like Tune-In.
