Hi all,
I’m experiencing a slow page transition in Ionic v4. I’m doing a navController.pop. It fades out 90%, then pauses for 0.5-1 second before completing the transition. It not only looks bad, but the page is non-interactive until the transition completes. It seems like the end of the visual transition, ngOnDestroy, and regaining interactivity all occur around the same moment.
I’m hoping it’s something obvious, because otherwise I may need to walk back a lot of changes to diagnose it. I did a large scale refactoring plus an npm audit fix before I noticed the problem. 
Anybody got any ideas?
TIA,
David
