For some reason, I can't pull up Autosport, "set back" meaning.....
A change of time?....removed altogether?
If removed, no "leak check" for some team(s) that may have had an off and needed major repairs? Walking into the race blind with "book" setup? Ouch.
If so, this is incorrect? (from LeMans.org):

Add the support races and Thursday will be hell on earth if you're working for teams in the 24 hours and Road to Le Mans race.

To be honest, looking at this schedule it's made te be run behind closed doors or limited access for public. I doubt the paddocks will be accessible, probably only (a part of) the village on the inside of the track. No time slot for a pitwalk on Friday, no mention of the parade in town ... Great British Welcome at St Saturnin has also been cancelled.
