I enabled UltraSwift Pay but it's not appearing on my form

UltraSwift Pay will only appear on your Donorbox donation form if the donor has a Google/Apple Pay account connected to their current browser or phone, and a valid card added to their Apple and Google Wallets. The donor is also required to be based in a location that supports Venmo and Mercado Pago. 

Once the above criteria are met, the Donorbox donation form with UltraSwift Pay will look like below (real example from the donor's end).

Additionally, here's how your donors can add a valid payment method to their Google account, and how to add it to their Apple account.
