Thanks for the detailed analysis. This may not be an issue anymore since we've started using Main.immediate there but I' not sure; I'll try to create a test case.
Description
Version used: Navigation 1.0.0-alpha08, Fragment 1.1.0-alpha02
Devices/Android versions reproduced on: Device - Pixel 1, Android Ver - 9
If this is a bug in the library, we would appreciate if you could attach:
My scenario is that between fragments I open an activity then comes back again. Until now it's normal works. But when I open the activity again that will cause a crash.
The error message as below:
