Description James 2015-11-04 12:09:29 UTC
As reported:

Put two buttons A and B on the same page and assign a PushAsync(PageA) respectively PushAsync(PageB) action on them. Press A and hold it, press B and hold it as well. Now let go of button A – PageA opens. If you now let go of B, PageB also opens.

Steps to reproduce with attached sample:
1. Open application
2. Deploy to device (easier to test)
3. Press one finger down on button A, hold down
4. Press finger down on Button B
5. Lift up Finger on A-> Navigates to Page A, keep Finger b down on screen
6. Lift finger B.

Expected Result:
Nothing happens

Actual result: B Button click is still registered and navigates to Page B despite the context has changed.

Seems to be happening on Android (tried an S5) but not iOS (tried an iPhone 6).

Thank you for your report. At this time there are no plans to implement any changes around this issue. This is pretty much how the underlying toolkits operate.

Warm regards,
