12/18 update doesn't work on airplay

Since the latest upgrade the KCSM app won't play on my speakers anymore, only on my phone. I love the station but I mainly listen at home through speakers, not my phone. Hope this issue can be fixed soon. The app is useless to me without this feature.

Terrible app, plagued with ads

This is among the worst apps I have ever used. I love KCSM and am a supporter. But the KCSM app ads are pervasive and cannot be dismissed. I tried the Safari browser on iOS and it’s even worse. There, the ads actually stop music playback until one acknowledges the ad. That’s totally unacceptable. For now, the only ways I know to listen are: 1) using a radio (such as in my car), and 2) through a computer browser with an ad blocker installed. From reading through many older reviews of the app, it has never been very good. This is in contrast to many other radio station apps that work flawlessly and are designed well. Why can’t KCSM get this right after so many years?

My Go-to Music Choice

The app is a fine way to listen to a GREAT station. I find the “dinner jazz” programming a bit backgroundy for my taste but all the programming is targeted to what most folks like at the time of day here on the Left Coast.

A special shout-out to their superbly knowledgeable, welcoming and up Music Director, and her get-you-going Morning show.
