I also faced the same problem today, the ATM generated an error receipt.
Had a chat with the support team, they said I was one of the affected users with this issue. They will fix it soon.
The agent did give a list of ATM banks that work, so it was quite helpful.
The list of ATM banks :
- Federal Bank
- Yes Bank
- Bandhan Bank
- IDBI Bank
- DCB Bank
- Equitas SFB
- AU SFB
- Punjab National Bank.
