In the Desktop version of Discord, if you edit roles on your server, you are warned about the changes that you have made to the role:
However, if you edit the same permissions on mobile, then there is NO warning, and in some cases permissions can be applied without your knowledge? I pressed the Back button on my Android phone, but I fat-fingered the Administrator permission on the general channel of my Discord, and then it went back to the role listing, without me any the wiser:
Because the Administrator privilege is right above the Back button, it is very easy to accidentally press and enable the Administrator privilege and then return to the role listing without knowing what you did. Please add a save button warning to mobile just like on desktop.
