This seems to be a similar problem as here:
But, I wanted to post it here as it's happening in iOS and not just on the Desktop client.
I have a playlist with 300+ songs, but when I listen to it on shuffle, I only hear about 50 songs shuffled over and over. This is a major problem for how I listen to music and why I got Spotify.
Is anyone else having this issue? I may have to drop Premium if this continues.
