Screen Overlay Detected

I’ve just signed up and installed the app but when trying to add the app on my Huawei p30 it comes up with Screen Overlay detected. I’ve managed to switch most apps off with it but something called System UI is turned on but it won’t let me turn off the screen overlay as the on/off button is grayed out?

Do you have night light on or eye comfort I believe it’s called on Huawei?

Or Facebook chat heads

No it’s turned off

Turned off as well only one that’s turned on is System UI but I can’t turn it off :weary:

Sorry can you explain what you mean by add the app,

This is the main UI app - it controls things like the status bar, etc. You can’t turn it off, it’s a critical part of Android.
