I see changes going all the way to the first week in June.
I can see them in EF too, but only one of my 6 reservations for the last 2 weekends in May and the 1st weekend of June is not allowing me to access it and saying "Sorry! This reservation has been cancelled. Error:400520414". The remaining reservations are still normal and can be accessed online, but are also Zeroed out in EF.
