Thanks for the response. It's a shame about the delay. It explains why it didn't happen with my previous phone, as I used the 3 navigation buttons. I decided to switch to Android's gesture navigation and overall prefer it. Just find the delay annoying. I thought about changing the animation, but have read that causes problems with the AOD and finger print scanner, so didn't want to screw that up.
In terms of the swipe up, I didn't make that as clear as I should. I have the general swipe up from anywhere to go to the app drawer, which gives me no problems. It's just the swipe from the home "button" that is a bit finicky. Though I just realized it's only when I'm trying to get to my main Home Screen from one of the secondary ones. It just requires a very very short swipe, or it does not work. It's fine when exiting an app though, so maybe not the end of the world. I'll just swipe left or right to get back to main screen in the future.
(I know all of the "swipe/gestures" verbiage gets a little confusing when trying to distinguish between Android's gesture navigation and Nova's swipe/gesture features)
