Scrolling stuck on IOS when using nested repeater

[SufyanAhmad]

I am using Xamarin forms version 4.0.6.8 and Grial 3 pro UXDivers.Grial 3.0.54 When loading items using a nested repeater. The internal scroll is working but parent scroll is blocked when scrolling.

Hi @SufyanAhmad I've been running certain tests but it's not clear to me exactly what is the problem. I think what you're saying is the behavior of the gif but I'm not sure Could you explain a little bit? Thanks!

@fcastro07 , Please see attached. Few patterns that I have observed:

1. It freezes every time the scrollbar disappears
2. It happens mostly (~70% of times) at beginning and end of vertical scroll
3. Changing the speed of scroll sometime solves the issue

iOS 13.5.1 iPhone 8 Plus

@khalid-halo , Even with this I can't reproduce the issue. Can you send me a sample to ?

We saw your issue. Now it's clearer where the mistake came from. We're working on a solution. I'll let you know when we have it!

@SufyanAhmad I think the issue comes from line 478 of that xaml. You have the following:

<grial:TabControl
     Grid.Row="1"
     IsVisible="{Binding Channels.IsFeed}"
     Margin="-20,-60,0,20"...

Could you change the -60 to 0 in the margin and try?
