Wallet Transit Card Option
I live in Washington, DC and our transit system WMATA just announced that we can now add a SmarTrip card to Apple Wallet and use it to enter and exit the subway system. I followed the instructions to do that in my 6S Plus by clicking the + symbol in Wallet but the transit card option isn't available. My phone software is up to date and using iOS 13.6.1.
