White screen on Ipad when trying to log on Spotify

I have just bought the djay 2 for my Pioneer WeGo 4. When I try to log on to Spotify on my Ipad it just get this white screen, My Ipad is old (maybe 6-7 years), but everything was fine before I tried to log on Spotify.

I also bought the djay pro because I thought djay 2 did not work, but is the same problem there.

Can someone help me?
