My EDD made the same change yesterday, then to 5-26 June this morning. Hopefully yours has shuffled forward a little, too.
Out of frustration, I did message Tesla Sales last night. Their response was the usual cookie-cutter stuff, including telling me how and when I could make payment (even though I have fully paid and done all of the paperwork). So, no help there.
I am curious to know whether Vedaprime has been helping you have a better sense of these changes, or are they coming out of the blue for you, too?
