Hi there, @sailho. 👋
Thanks so much for posting on the Pandora Community.
I do see that you're upgraded to Pandora Plus. For Pandora Plus subscribers, we will automatically choose up to three of your most-listened-to stations along with Thumbprint Radio and add them to your offline listening stations.
Are you using your iPhone device when you notice the green arrows? If so, those green circles with the downward pointing arrow indicate that those are the stations downloaded for offline listening.
You can find out more about how offline listening works here: Offline Mode + Downloads
Hope this helps! 🎧
