After one of the 1.17 updates I’ve noticed that the extra buttons on my mouse are no longer mappable and button5 doesn’t exit, this problem has been happening for a while and I finally decided to make a review.
My friends have also have this problem and it seems it’s happening to only Xbox consoles.
Thank you for your report!
