Consider switching banks. It's really easy with the "current account switching service" (they close the old account, redirect any payments to the new one for 13 months, and switch over all direct debit and standing orders).
That that service exists shows they're not quite the dinosaurs you imagine.
Unfortunately I am abroad very often, so it's difficult to find the time to switch banks. Also, I checked the mobile apps of other banks and they are even worse.
