Often, you don't, because the same developers of the bank app decided it's an unnecessary power user feature that doesn't fit in the MVP or something.
Or, even if they add it, there's no way to save the file, only to "share" it, which 99% of the times isn't what I want, and I'm frankly tired of routing through the mail app as a workaround. At this point, at least on Android side, there exist apps whose sole purpose is to be a share target and dump the information to file (and being apps on an app store, chances are top 10 are just thinly veiled malware).
Yeah I wondered why anyone would ever install such a simple utility app from the app store. It's something that needs to be developed once and then only receive minimal maintenance which means the usual individual maintainer scratching his itch and sharing the result model works well but it also processes intentionally sensitive data meaning developers might be tempted to monetize that in some way. The curated open source distribution model of F-Droid is the perfect solution to this.
really? I'm not suprised by shitty developers developing shitty apps but i'm still baffled. Surely the bank would be getting tons of angry emails from customers if it happened in europe
They probably support proper export for business accounts. Business customers have leverage. Regular people? They're an annoying but necessary nuisance.
