XCode 12 built code reenables idleTimer on iOS 13&14?

I see a weird bug. I have the following code:

Code Block       func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
            application.isIdleTimerDisabled = true
            ...

Code Block
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

application.isIdleTimerDisabled = true
...

However, this has no effect on some iOS devices. This was not the case before when code was built with XCode11.x. Is this a known bug?
