I'm using a Huawei P9
EMUI version 5.0.4
Android version 7.0
I cannot open the settings menu for do not disturb, in the actual settings main menu when I press do not disturb to get into the settings it doesn't open and settings itself minimises and I get sent back to the home screen and if I try to open it from the drop-down menu by hold pressing it doesn't open either.
I would like to know how to fix this as I can't currently change my list of contacts that can disturb me because that option is in the menu which, to me, is inaccessible.
I made a screen recording and a YouTube channel because I can't just upload it:
