In my country, partially due to sanctions, you can access the bank via browser and receive 2FA codes on $15 dumb phone. Also why do you need bank app on your phone? Do you like to give money to random strangers on the street? Only scammers need money urgently. Also it is not secure to use the phone as a single factor to access the bank.
I do not have any bank apps on my phone (it is not even connected to the Internet) and I have no problem.
In a town nearby me (not really near me but within an hour's driving distance), sometimes I will see old people selling fresh fruit/vegetables in their front yard. They typically take cash, Cashapp, or Venmo. It's super convenient to be able to use Venmo in that situation. These are people I haven't met before.
I can do everything on my bank app from prepaying small amounts of a loan, spend analysis, opening fixed deposits and such.
Some banks require 2FA through their phone app to login to internet banking on the computer.
App can work as digital money without card reader, maybe even free, like bitcoin.

Many banks gate features like mobile check deposit behind the native app. The nearest ATM is 20 minutes away from my house, so unfortunately I consider this feature essential.
