Application crashes, pullToRefresh component is a reason

[DmitriySmirnov]

In logs I see the following error:

What version of forms and of the pull to refresh are you using? Can you just bring the library into your project and test it? I am using it currently with 2.1.0-pre2 with no issues.

Fixed in latest nuget update in about 10 minutes

Hi James.
Did you publish code changes on github? I don't see new commits here.

Hi James.

We still see a lot of crashes in our Xamarin Insights. Could you please help us.

I would open a new issue. Seems like this is a bit deeper in the animation system, are you doing something to it?

[SlavaChernikoff]

I created a new issue :)
