Button mapping

Thank you for the answer it is not an elite controller so that answered why it defaults back due to it is a plain xbox one controller was just curious on why it kept defaulting back

You probably can't switch the assignments, as technically, the RB Button is a digital on/off button, whereas the RT Trigger is seen as an analogue axis. Switching these on a system level, would make multiple games unplayable. If a game like Overwatch allows
remapping, because they "know" that the new button/trigger mapping won't break anything.

But the console won't know if you don't start a driving game after your Apex session, which would cause your car to only allow full throttle or no throttle.

If you require hairtrigger precision in your shooter games that don't allow for remapping, you might want to invest in an

Xbox One Elite controller, which has a small switch, that will move the trigger boundary further to the front, so the trigger feels and acts like a digital button with less travel.

New September 22 update has fixed issue. Thanks for quick action Microsoft

Same problem here ! I need help too

As of 09-19-16, I am experiencing the same issue. The "done" button within the Xbox accessories app is non functional. Restarts, controller swapping, factory reset, as well as hard resets did not solve the issue. For people with disabilities, like myself,
this feature allows the purchase of games that would otherwise go unsold. The ability to re-map buttons game to game is a crucial quality of life and accessibility feature for myself. That said it is highly discouraging to not be able to play some of my favorite
games at the moment due to this feature not working.
