Apple

I was surprised how quickly it filled up without me even thinking about it that I ended up disabling it. I just wish syncthing equivalents were better supported, since my Android, Microsoft, Steam Deck, and MacOS sync files without me having to really think about it.

But, iOS and iPadOS due to file access restrictions don't work well with it, so it's like they try to push you into iCloud by making everything annoying when it comes to files sync even with just the base iCloud. Good thing though is I just use an iPad now, which I use more as a media consumption device. No need to deal with iPhone annoyances, which would be much more important in trying to sync and transfer files as a multi platform user.
