I have a question about the Sonos API authentication redirect URI. In previous projects I have used a redirect URI that my native application can intercept. Such as myApp://auth-code. That does not appear to be possible with the Sonos API as it expects the redirect URI to be publicly routable and HTTPS. Must I have my own server that sits between my native client and the Sonos API? I have a feeling I may be missing something simple here. Thanks for your time.
