Change the default “move to” folder in mail iOS

This has been going on for some years without a change. And quite some people have the same issue.

The fancy “learning mode” of the mail system on iPhone and iPad does it work too well it seems. So the moment it thinks certain messages should go to a certain folder, it never changes that anymore. It stopped learning. And -most importantly- there’s no way to reset or change it manually.

A nice feature becomes a frustrating setting.

There is no solution and in the (link to) proposed product features, weirdly enough Mail is not mentioned in the iOS section?! (It is in MacOS.) Safari is, as most other programs and apps. So I’m not surprised they never worked on it if they didn’t get the idea or complaints.

How can we get Apple to know this issue exists and get it prioritized and to the development team?
