Joint bank account with online banking etc

[gravity101]

Which banks offer joint bank accounts where both parties can have access to an app with QR code payments and everything else that comes with online banking? We have a joint account with K bank but they only allow 1 person to have an app, pay from the app and to control the account from it. All we really have jointly is 2 ATM cards. Kind of defeats the objective, especially in this era of a cashless society. Anyone have any joy in setting this up? My SCB and the wife's have also said they can't do that. Seems weird, I can't believe couples have to have separate banking lives here.
