It appears the problem is that our present RedirectURI mixonset:// is no longer accepted.

We've already added a new RedirectURI mixonset://spotify although it seems not to have taken effect yet.

Could the Spotify team fix our original RedirectURI, or update our new one soon?

This issue also suddently occurred without warning today for me. 

@Zeyu, was the solution to simply append "spotify" at the end of your direct URL for the app to accept it?

Adding "spotify" to redirectURI solved the issue for me.

The only question: how did you know that you should add "spotify"?

(sorry, it was a duplicate message)

Good to hear @litvakle 🙂

If you were using the basic url xxx:// without anything after that too, it's probably just considered not secure enough. So it doesn't have to be xxx://spotify, anything probably goes

Anyway even after updating this it hasn't worked for us yet, which login method are you using?

[litvakle]

Not sure I fully understood your answer 🙂

I'm using this URL to authorize via the Spotify App:

"spotify-action://authorize?client_id=\(clientId)&redirect_uri=\(redirectURI)&response_type=code&scope=\(scopes)"

And I also added the new redirect URI in the Spotify developer console here https://developer.spotify.com

I am also experiencing this problem. I cannot access Spotify through Mixonset through my desktop or on mobile.

@litvakle What I meant is just that Spotify probably considers our previous redirect URI mixonset:// not secure enough, so now we have to set it to mixonset://spotify or mixonset://spotify-login or something else.

Strangely we were using the same login method as you did, although it also stopped working even after fixing the Redirect URI, so we needed to switch to PKCE instead. But good to hear it all works now!

@Juliaggustafson - we've fixed this already, and you can get the fix by updating your app in the App Store now. Thanks!
