Hi Emil, 
 
Due to limited working days, we haven’t released weekly NuGet on 29th January. So, the fix will be included in upcoming Volume 4 SP1 release which is scheduled by first week of February 2019. 
 
If you want patch for this issue "Exception while navigating away from the page in Android", you can download this from below location
