Congrats! I also got the April 29th notice earlier this week.
I was wondering who your installer is for the EVSE? Mine is Evergreen Power Systems, and I have not heard boo from them. I even wrote, and nothing back. I am wondering if they are just super backlogged with install appointments?
Edit: Just checked again, and have been moved to week of April 18. This occurred within the last hour.
Edit again: Not sure if this constitutes cruel and unusual punishment, but I logged in again, to show my wife and send an update to the spreadsheet, and I am back to April 29th. I also noticed that the account page is running slow, so I am wondering if they are doing a large-scale update of dates for other folks, and mine was a hiccup. Either way, hopefully this means good news for all those who are awaiting good news.
