I upgraded to a Featured Listing but don't seem to have any of the features

Upgrades are automatic the instant we receive payment. Delays occur if you send an eCheck by PayPal.
PayPal will send an eCheck instead of an Instant Payment if you have a bank account associated with your PayPal account rather than a credit / debit card.
PayPal takes time to process an eCheck before they send us payment, they will always give you an estimated date in their payment notification emails.
