Older builds from Apple's App Stores are always available for older devices. The _trick_ is to download them with an App Store user that already "bought" the app and from the "purchased" section and from the device with older OS. If _all three_ are true the Store will offer to "load the newest version that can be run on this device".
This is true for every application, unless the developer did not explicitly marked older versions as "unavailable" for everyone.

A new test build of the iOS client for Radio Paradise is now in beta. It contains the support for Shortcut that many people were asking for. After selecting a playlist from the channel selector, a shortcut can be build to automate the playing of the channel.

ie: Shortcut -> New command -> Search for Radio Paradise -> Select the Play Action.

The Action can then be attached to Siri or to other automation triggers.

Let us know if it works for you (it should) and if there is some other commands you'd like to see implemented. Write here, or use the feedback mechanism in the application itself (Settings -> Feedback)

You can get the test build from https://testflight.apple.com/join/ieYKbfZv (follow the instructions there). You can always get back to the “normal” build by reloading the app from the App Store app and/or opting out directly in the TestFlight application. No information are transmitted by using the beta but the crash logs (if any and through Apple) and whatever you decide to share as feedback.

After installing and starting the app (and selecting a channel), allow 10/15 minutes for the shortcut suggestions to propagate through the system.
