I have an app that I have "inherited" to maintain.
Since the iOS 11 update, on two separate iPads (iPad Air and iPad 5th gen), I have a problem. Both devices are running iOS 11.0.2.
When the app is installed and launched for the first time, the app icon shows up in the "Recent apps" section of the dock, but the icon is grayed out and cannot be tapped (it can be dragged, but long-pressing does nothing). For any subsequent app launches the dock icon remains unchanged, unless any process occurs that causes the app icon to go away from the "Recent apps" section (opening a few other apps or dragging the icon to the left side of the dock) then the icon is no longer grayed out and it becomes tappable. It looks the same as if the icon has been tapped, but it is permanently in that pressed state (it does not trigger a long press event).
The problem occurs when the app is installed from the App Store, XCode (Debug session) or Crashlytics. It re-occurs after uninstalling the app and re-installing, even if the dock icon was "fixed" during the previous installation.
The home screen app icon is fine (not gray and can be tapped).
See the image for what the icon looks like.

This turns out to be (what appears to me) an iOS 11 bug. A few other devs have the same issue. However, I have been able to replicate the issue with my own app installed from the App Store. Also I managed to get the bug on the Google Play Music app.
