From now, Spotify does not support Windows Phone
Microsoft actually does not care about Windows Mobile, and if Microsoft wants to compete with Android and iOS, they need to do something instead of sitting and doing nothing.
I know they improved the Windows Phone over years, but Windows 10 Mobile was not enough. Even if they improve the Windows Mobile, the other developers do not care about Windows Phone. If you have ever used Windows Phone, you know that there are limited apps. You cannot either find the popular apps that you can find on other platforms or these popular apps are not upgraded for a decade.
If you are using Spotify, and Windows mobile, it is a bad news for you, because Windows Mobile will not be supported by Spotify from now. You can still use the app, but there will be no updates.
