Payment Sheet input validation incorrectly marks account numbers as invalid.

[timleyden]

Describe the bug
After moving from elements hosted on a web page to the react native sdk with payment sheet we got several reports that stripe was not allowing users to enter bank account numbers. After investigation we found that several banks in Australia have 6 digit account numbers. When a customer enters this valid number they cannot proceed and receive a validation error stating the number in incomplete

To Reproduce
Steps to reproduce the behavior:

1. Go to payment sheet with payment method type becs enabled
2. Click on 'AU BECS Direct Debit'
3. Scroll down to 'Account Number' and enter only 6 digits
4. See error

Expected behavior
except 6 digit account numbers
alternatively automatically padding with 0s but this may lead to confusion

Hi @timleyden Thanks for flagging this problem.

The account number validation logic is from the underlying Stripe Android SDK. I've already informed the Stripe mobile SDK team about this problem. Once this problem is fixed in the new Android and iOS SDK, you can just remove yarn.lock file and run yarn install again to download the latest mobile SDK.

Hey @timleyden! This was fixed in this PR and released in v21.0.1. Please re-open if you continue having issues.

Hello @samer-stripe and @seanzhang-stripe! I believe we should still open this issue cause it is still happening on iOS.
