Had to delete/reinstall the app to regain storage space

I’ve seen the other threads about “Recently Deleted” but the files (downloaded from my NAS to my iPhone) I deleted did not appear in Recently Deleted in Files app. There were no files there at all.

I had to delete and reinstall Infuse (thank goodness for iCloud sync!) to regain 6GB of space.

Just thought I would mention it.

That sounds like it was your metadata storage, not a deleted file stuck in recently deleted.
