Hi Team,
I've tested this and it is currently breaking as described in this issue. I found this is due to the same reason (Effective value of Flyout is being considered as default before the content page is rendered) and the same is described by here: https://github.com/xamarin/Xamarin.Forms/issues/7985#issuecomment-542461011

This issue is related to #7985 and I strongly believe will be fixed by the PR #8135
@PureWeen Would you mind testing this use-case with your fix?

Thanks!

If this is really fixed by #8135 then we should be able to verify that with the new 4.3 service release :)

@tsjdev-apps would you be able to confirm this?

Hi @jfversluis,

thanks for the reply. I just tested once again with my own application and the template. And it is working with the latest Xamarin.Forms version 4.3.0.947036.

I will close that issue now.

Thank you for verifying it!
