Question about Apple MacBook Pro 13 – Late 2020

"The current delivery time is approx. 2 - 4 days. (No responsibility taken for the correctness of this information) " Does yesterday's statement still apply today? The delivery date has changed several times in the last few days. Do you get a promise and then another cancellation the next day and so on, or why does the delivery date change so often within a short period of time?
