I have loaded the IHeart and Pluto Tv apps in Roku. When I click to open the app, the "opening app" wheel just spins and spins and never opens the app. I have added other apps with no problem. Are these not available in some geographic areas? I live in Puerto Rico.
If removing the channel and adding it back after you've restarted the device does not resolve the channel issue, I'd recommend reaching out to channel support directly to report the issue and request additional support. Many channels on the Roku platform are developed and maintained by the channel provider directly, and they'll be able to best assist. If other channels are working correctly, and you only experience this issue on that channel (app), that is likely an indication that the issue lies within that particular channel. In these cases, the channel provider will need to investigate the issue in order to help resolve it.
