Yeah agreed.
On my Mi 11 it is enabled, but on my 12 Pro it isn't (probably because of where the front camera is) even though there is plenty of space for it (or just put it on the other side like the DND mode icon)
Works fine so far on my Mi 11 and 12 Pro, but the scanner icon in the control center disappears after a while. This has been the case since the last 5 ROMs (or even longer) and it is annoying because I use it a lot and need to add it to the control center again and again
1: You don't need to get rid of it. It is just a TWRP issue and your ROM is already flashed fine. You can safely ignore these errors.
2: Read the changelog in the 2nd post
3: Use a different TWRP version by a different developer if there is any.
Installed on my XM 12 Pro and Mi 11, so far so good, but the Launcher sometimes randomly reboots and resets the clock theme.
Edit: seems to have something to do with super icons since they also reset
Installed on my Mi 11. All fine so far. Will update this when there is something important and when I installed it on my XM 12 Pro.
Edit: works fine on XM 12 Pro
Working fine so far on my Mi 11 and XM 12 Pro, but the settings still shows there is an update available, but I'm sure it'll go away just like in the last ROM
It's not monet icons since it doesn't pull the colours from your wallpaper (or repainter). Also, this theming implementation is very weird. Some apps with working Meterial You icons don't apply this theme, while some other apps do. Very weird.
Can you see it in settings > apps manage apps?
Make sure to click the 3 dots on the upper right corner send select "show system Apps" (or something similar)
