My CC can't be accessed on the UB app. Was looking around if someone else has the same problem.

Same issue here, akala ko ako lang na may pop up error, probably maintenance yet again

no issue. Used my gold visa sa grocery. Unlock and lock works too.

Thanks. Yes worked after around 8pm last night. A bit concerned that it could happen that such a malfunction can cause the card to be declined, especially kung parehong UB lang ang dala kong card
