How does one login with an exsisting Spotify account on the Windows 10 Mobile app?

[3limin4t0r]

I recently made an Spotify account using the webbrowser. I installed Spotify on my Windows 10 Mobile, but I can't seem to login with a Spotify account. Am I missing something? Being able to login when starting an application seems like an mandetory feature.

You can see the screen I face in the attachments. There is nothing more if I scroll down further. What you see in the image is all there is.

(edit / solved)

I found the problem, I think it jumped outomaticly to the register page. I had to press back one and was able to sign in.
