TBH, I’ve never quite understood the review flow & I don’t know how to find / review things that have already been handled.
When I see a red flag in my notifications, I go handle it, but otherwise, I tend not to touch the things I can find because the controls don’t seem to do what I think they will.
For instance, if I see a visible post with the flag icon on it, I get curious, but clicking on the flag doesn’t give me the details - I honestly have no idea how to get the details - it just re-flags.
