Large downloads to an app showing as system usage
I use the Tidal app. I download hifi or master albums for offline listening. The first time I did this the 10GB of downloads showed up under the Tidal app in iPhone storage, as expected. The second large group of downloads I just did shows in the app itself, but is shown under system files in Settings|General|iPhone storage instead of under Tidal storage as the first large set of downloads did. At least I’m assuming the downloads are showing under system usage, since they aren’t showing up as Tidal app usage, and I can’t think of what else would have increased my system usage by 15GB. Any thoughts on this?
