Schedule function doesn’t work

Hello,

I want to send emails on a specific time in the morning (7:00), but when i try to click on “schedule”, that function doens’t work. I can’t choose a specific date and time on which the e-mail will be sent automatically. Is it because i’m using mailpoet 2 in stead of mailpoet 3? Or is there another solution?

Kind regards,
Vanessa
