Just before covid - Louvre's timed entrance was very flexible once admitted. For example, if my timed entrace was in the morning, I show up at my time, visit a wing or two, leave the area, and then return back to the museum later that day to do another wing without any issues. Coming in and out of the main museum with my tickets was fine, so as long as I am not trying to reaccess the wings I already visited.
Has anyone been there since they re-opened post Covid and can confirm this is still true?
