Switching from app to app on iPhone XR with VoiceOver

With my old iPhone 6 I was able to swipe left/right with 4 fingers when using VoiceOver to switch easily and quickly from app to app.

This seems not to work on my new iPhone XR.

I'm wondering if there is a different gesture we are supposed to use for this when using VoiceOver on the newer phones. When I get into the 4 finger double tap help, the phone says that swiping left/right with 4 fingers should work, but it doesn't work for me when trying to switch from the News app to my Mail app.

For sighted users it seems like they can simply swipe with one finger from left to right on the bottom of the screen to switch apps, but obviously this wouldn't work when using VoiceOver.

Thanks for any help.
