Regression
No
EventSystem.current.IsPointerOverGameObject(touch.fingerId) always returns false in Player
To reproduce:
1. Download attached "NewRepro.zip" project and open in Unity
2. Open "HelloAR" scene
3. In Hierarchy go to PlaneDiscovery > Canvas > Text and change Text Component Color to Dark Color
4. Build for iOS
5. Deploy the Xcode project to the iOS device
6. When App is deployed press anywhere on the Screen

Notes:
- This issue happens on both Standalone, iOS, Android (Mono and IL2CPP)
- This issue also happens even tapping on the UI GameObject
- This issue only occurs when you build from a clear Project which means no Library folder

Hi
I don't see it fixed in 2019.3.6f1, IsPointerOverGameObject() with touch finger id always returns False as there is no UI touched.
Tested on iPhone 7.
Please suggest

Latest issues
- Frame Debugger's Hierarchy is not navigable when connecting it to the project built with the Volumetric Fog
- The number of SetPass Calls is increasing when attaching the Frame Debugger to the Player
- Scrollbar briefly appears in the Package Manager during installation process even when the package list is too short to require scrolling
- Script resets to use the previous Skybox color when saving the Scene changes
- [2D] Sprite Library Editor window throws NullReferenceException error when entering Play Mode with Game View maximised
Resolution Note (fix version 2020.1):
The EventSystem Update() function should be called first before the Update function() on any of the User scripts.
When a Library folder is deleted this order is lost, and the user script gets the Update() call prior to the EventSystem and as a consequence the current bug comes up
Hence it is not recommended to delete the library folder.
