My Question or Issue
Dear spotify, please fix search case sensitivity for Cyrillic alphabet. It's been at least 2 years since this problem has been reported both in mobile devices and desktop enviroments. This is unacceptable! Fix this at once!
You disregarded the post I link below for no reason, but I'll tell you that the problem persists both on my Windows desktop and Android phone and I'll suppose it is the same for Mac and iOS devices. Shame on you!
