I recently got a payment request to pay for a Christmas event.
I clicked the link it took me straight to the payment page and I was quickly and easily able to make the payment.
Afterwards I realised that I had made the payment from my joint account rather than my personal account. It would be really great to be given the option which account I make the payment with. I think normally I would make a payment from a specific account page, but in this case the payment link deep links me straight to the payment page in the app for whichever account I was last looking at.
