I can't log into spotify

I just found out about the spotify feature and I’m at the part where i need to login from the djay app but when i click on log in to spotify, nothing happens. I tried uninstalling and reinstalling but that didn’t do it either.

A new Safari window should open up when you tap the login button.

Please open the Settings app on your iPad, go to General > Restrictions and make sure that Safari is not restricted.
