Premium user here. I'm using Google Fi and have a limit of 1gb per month since I'm on Wifi nearly all day between work & home. I'm only a couple of days into the current months plan and Google warns me that I've blown through over 350mb of my plan already just today while I'm driving.
Since I'm a premium user I always download my playlists onto my phones SD card so I don't burn through my data while driving. I haven't changed any options on my phone or within Spotify. Spotify's option, "Download using cellular", is unchecked just as it's always been. Basically it either downloads via Wifi or it doesn't download ... until today.
Anyway, I was in my car and got to the store I was heading too. I noticed that 3 of my smaller playlists weren't downloaded any more. I checked off "download" expecting it to queue up for the next time it was on wifi. It started downloading immediately. I ended up dumping my phone into airplane mode for it to shut down.
When I got home I took it off airplane mode expecting everything to be fine. Fast forward a few hours later and Spotify has burned over 700mb of my 1gb plan.
So as of right now Spotify has effectively blown through nearly 3/4 of my data plan for the month which has only just started. Again, the switch for "download over cellular" is unchecked so this shouldn't have happened.
Considering this is going to cost me a few bucks this month I would take it as a kindness that Spotify waive this months premium cost.
