I wonder if it might be possible to have a different sound effect to play if a payment fails? Today I didn’t realise I was short of cash (a push notification would help) but the sound was the same so I assumed payment had gone through and I left. It would certainly help me and save embarrassment. Thanks.
Like when you get a question wrong on a quiz show.
Waaa waaa waaaaaaaaaaaaaaaaaaa

EEEEE ORRRR
Completely agree with this. It can also be quite shocking when a Bill Split request comes through and it sounds like a payment has gone out of your account.
There should be different sounds for:
-
Successful payments.
-
Failed payments.
-
3D Secure requests, Bill Split requests, money requests and Shared Tab reminders.
-
Other notifications (eg: not enough money for Direct Debit coming out tomorrow, Spending Reports, Travel Reports etc…).
A difference between successful and failed is a good idea.
There are already different notification categories for different things, and I’d expect a lot of the other ones mentioned to come under extra or important… on the android app they are currently:
Credit
Debit
Extra
Important
Spending reports
