Whole Foods delivery via Prime Now - no delivery windows?

[DisneyFave]

Is it normal for Whole Foods via Prime Now to not show any delivery windows for the next day? Can you only book delivery same day? The app says all remaining windows for today and tomorrow are unavailable and to check back tomorrow.

It means other people already chose all available slots for your desired day, and that you would have to choose a different slot/day, or else a different company.
