Not really. There's a difference between the local copies of iCloud photos and actual local saves. Like I said: try editing one of the photos that's actually part of your photo stream, not a local save. You can't. You have to create a copy first and edit that instead.
So, WHO doesn't know how it works again?
YOU. You don't know how it works. I've explained several times that this launch was botched and missing key elements, yet it still works mostly the way it is supposed to. Try to keep up. Bye now.
