No space left on iCloud Drive. Impossible to delete files.
So at some point I had a big folder on iCloud Drive (I upgraded to 200GB once) and then downgraded without removing anything. Now my iCloud Drive is full (it says it's using >50 Gb even though I only have 5 Gb available) but I can't find a way to delete those files.
I saw the big folder once under the hidden folder ".Trash" in iCloud Drive and I erased it manually but apparently it wasn't reflected on the server.
Any help would be appreciated!
