What to do first
Donation Central points players to the in-game Pending Payouts frame and Roblox transaction history. Its current Roblox description says earnings take under 12 hours to enter an account.
For Donation Central pending payouts, first open the game's Pending Payouts frame and confirm that the donation is listed. Then check the Roblox transaction record for the same purchase. Donation Central describes its donations as game-pass transactions, so Roblox's transaction information is the relevant external record.
The under-12-hours note is the current official game-description guidance, not a guarantee for every Roblox transaction. If either record is missing or looks wrong after that window, keep the purchase details available and use the official Roblox game page or creator-owned support channel when one is published. This fan guide cannot see private account or payout data.
