I'm not so sure. My bank would accept an address change over the phone for 'telephone banking' customers, which is no more secure than an in-app chat. Even if they required me to upload proof via the in-app chat, that would still be 100x easier than the process I had to go through with my bank.

Obviously banks have a lot of regulation they have to comply with but I think a lot of it is simply a case of "that's how it's always been" and a lack of competition due to the high barriers to entry.
