Using iPhone 6+ (latest version)

Spotify is on latest version I believe (5.0.0.992)

Recently added just 4 songs to my custom Playlist which currently has 333 songs, I accidently hit the offline mode switch on the phone and now it doesn't download anything from my computer. Offline mode is enabled on both devices, closed out of Spotify several times on both as well. Connected to the same wireless network, and plugged into my computer. What's the deal yo? This is the only app I pay for and I'm surprised I am having this issue all of a sudden. Never once have I complained until now. Yes I have enough space on the phone for it to download (2.5gb free).
