Removing a ViewCell from a TableView and then adding it back again results in the Switch control in the ViewCell being non-visible. The sample project attached contains three ViewCells, each with a Switch. When ViewCell 2 is removed, ViewCell 3's Switch moves off screen and seems to become Enabled even though it was previously disabled.
Setting a breakpoint to a position in the code after removing the ViewCell, you can look into the TableSection's children and observe that the IsEnabled property is set to false, even though the screen shows the Switch enabled.
Rotating the screen makes the Switch appear again. This issue occurs only on Android.
### Steps to reproduce
1. Download sample app
2. Run sample app
3. Tap ViewCell 1's Switch
4. Rotate device
5. Rotate device to original position
### Expected behavior
Switch in ViewCell 3 stays disabled and does not run off screen.
### Actual behavior
Switch in ViewCell 3 appears enabled in app and goes off screen. Rotating device brings it back on screen.

The customer reported this issue on a Samsung Galaxy SIII Mini. I've been able to reproduce on a Samsung Galaxy S5 and a Motorola Moto E (2nd Gen).
I was unable to reproduce this issue on any iOS device.
This is a issue with TouchWiz, shouldn't be present in the AppCompat backend, hopefully.
This should be fixed in 2.2.0-pre1.
I have checked this issue with Xamarin.Forms 2.2.0-pre2 and its working fine.
Hence closing this issue.
