Did any one receive pre-order shipping of Rachio 3?

Ordered 16zone+Flow meter+ enclosure combo on April 1st, payment method charged on the same day, till now did not receive any shipping info specific to my order. Entered a support request on Apr 25th got a generic response that would be shipped in 2 waves Apr 30th or May 7 week. Dont understand why it would be difficult to predict shipping schedule by order date one/two week before the actual shipping.
