How do I actually get paid? Is there a payout setup?

You need a payout account on file, and it has to be verified before money moves. Until then your payout status shows "Under Review," and you'll be notified once it's approved. After verification, Snaptide disburses your 75% share of paid downloads according to their payout cycle. If your status has been stuck for a while, there's a dedicated Payouts department in the support ticket system — they're responsive, and payout questions are exactly what that queue is for.
