Rent redemption requests are typically processed instantly but may take up to 5 business days to process in some cases. Rent redemption may take longer over weekends and holidays. Please ensure you have a phone number connected to your Atlas Earth account and that you can access that phone number. 

If your request for rent redemption has been approved, try tapping on the "Redeem" button in the Rent Redemption History section, it might be grayed out. Doing so should lead you to the new rent redemption system.
