tvOS 14 ate 13GB disk space?

[s2s]

32GB Apple TV 4K.

Before upgrade, used disk space around 12-13GB. After upgrade it became 26GB.

Checked disk space usage by 2 different apps, all gave same result.

is that just me? Or tvOS 14 really needs so much storage?

Just checked usage on mine, it is 13.5GB used and 16.16GB free. Don’t think that is much different than before I upgraded.

I think the issue was from Aerial video.

I enabled Aerial screensaver and weekly download new video, did a count, I have 90 Aerial videos downloaded in my ATV... each video can be up to 980MB so it explains why disk space was taken, somehow in previous tvOS this disk usage isn't reported...

Although someone said ATV only keeps 3-5GB Aerial videos at any time (https://discussions.apple.com/thread/250889239), apparently it is not true.

But I couldn't find a way to delete those downloaded videos.

So I did a factory reset and installed back all apps, turned off Aerial video download, ATV disk usage is now only less than 7GB.
