It’s not previewed yet on their instagram but all sneak peeks go out in the morning now per DAC, regardless of when the preview will be released on Friday. So there is a good chance you’ll see one that hasn’t been previewed but will be later in the day each week 😊
9:30 PT and 12:30ET are the same time just in different time zones. But yes that is the general release and it hasn’t changed for weekly releases! Hope that helps!
