It’ll save the new card for the app when you log in next time. App is terrible and broken BTW. You can’t see your bill. Fix it! ### 1/5 — Payment method *2020-12-22, version 1.0* Can't even add a payment method due to it not accepting an expiration date on card. Doesn't show how it wants the month and year and tried multiple ways. ### 1/5 — Awful *2020-11-25, version 1.0* This garbage app is terrible. ### 2/5 — App broken can’t View Bill *2021-03-19, version 1.0* Can’t view bill when you retrieve a bill it goes to a blank page been like this for years. ### 2/5 — Great Idea but still can't see my bill *2016-06-08, version 1.0* This is a great idea but when I try to view my bill all I get is a url address that doesn't work. Please fix this issue quickly ### 3/5 — Buggy App *2021-07-22, version 1.0* Balances on bills do not add up. Card number errors with the date which make me late on my bill. For the first year ran great but now it is constantly crashing or not working at all. Trying to redownload it now. Just needs some bugs worked out and it would be ok. But honestly, right now it’s just giving me a headache trying to pay my bill. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
