Hi @Shiloh (Loh) l24
Kindly double-check if the downloadable link was added correctly to each button. You can see this by going to your landing page editor>> Settings>> Edit email contents". Each of the buttons should have downloadable links. If they already have the links, but it's still not working, I recommend that you send an email to firstname.lastname@example.org so the team can take a look at your account.
