Offline playlist doesnt synchronise

[Jelmel]

Hello I have some troubles for a long time. My playlist doesnt synchronise for offline use when I have some new songs in it. I am trying everything: my iPhone is charging, my wifi is on, spotify always open. I've updatet spotify, i have reinstalleted. Nothing happens! Can you help me with that? Thank you.

Do the tracks have an orange exclamation mark beside them?

[Jelmel]

Yes. Only one at once! R

How much free storage space do you have on your iphone? The exclamation mark usually indicates it is running low. Spotify rcommends at least 1GB of free space.
