Should be fixed in 1.3.2-pre1
This is NOT fixed in forms 1.3.2 pre-1. Note: we are using timers for animating controls; For example we use FadeTo to fade controls in and out. These are paused while it is scrolling even in 1.3.2 pre-1
Per above comment, it does not appear fixed in pre 1. confirmed in test case
I have checked this issue with Xamarin.Forms version 1.3.2.6309-pre2. and observed that its working fine at our end. Screencast: http://www.screencast.com/t/5d1bOMAByLx
Please reopen this if you getting same issue.
Hi this is fixed for Device.StartTimer but not for FadeTo and i'm guessing other animations. Please apply the fix for all animation timers I will email an updated example with the problem
