Apple TV Aerial screensaver not downloading or updating
I got my brand new Apple TV 4K (2021 home theater model) the week it was released, and I'm enjoying it tremendously, but there is an issue that bothers me and I can't resolve: the Aerial screensaver is not updating at all.
I have tried every different setting. I have changed it from "update monthly" to "daily" to no avail. I tried every download option available and it made no difference. I've already reset the Apple TV 4k box, which was a pain but did nothing. To date, I still only get the 4 stock Aerial screensavers that came with the new Apple TV, and I'm unable to download new ones. Nothing I have tried worked.
Yes, I have a strong internet connection (Apple TV is connected via ethernet).
I have plenty of storage space (over 60 GB).
I have the box set up to update the software automatically.
I have also seen the advice provided in other threads, which has made no difference:

In case it helps, I don't have my system set up as HDR, in case that has anything to do with it. My TV takes SDR but not HDR.
Is this a bug with tvOS 14.6? Will this be solved with version 15?
Please help. This is frankly annoying at this point.
