Should be fixed in 2.3.3-pre1. Thank you!

I have checked this issue with Xamarin.Forms 2.3.3-pre2 and its working fine.

Hence closing this issue.

See https://github.com/xamarin/Xamarin.Forms/pull/600
Comment 5 adrianknight89 2016-12-17 00:34:12 UTC
I think we need to use PopToViewController in addition to PopViewController to fix this.

I am seeing this issue in 2.3.5.239. Confirming and we'll give it another look.
Comment 8 Diego 2017-08-10 15:44:23 UTC
This issue is still happening in the latest stable Xamarin Forms version 2.3.4.224 so far.

Is there any workaround using custom renderers or any other way?
