Plan: Premium

Country: USA

Device: iPhone XS

Operating System: iOS 12.4 (latest)

Spotify App Version: 8.5.19.947

My Question or Issue:

Has anyone noticed super high data usage when streaming music using the automatic setting ? Spotify used 9.1 GB (Gigabytes!) of data in a six hour timeframe on my iPhone's Spotify app on 8/16/19. That is insanely high and unusual. I am working with Spotify Executive Support but wondering if anyone else has run into high data usage problems. My understanding is that the app should use maybe 40 to 150 MB per "hour" based on quality settings. Mine used 1.5 GB per hour yesterday.
