Push notifications slower on 1 iOS device than the other?

Noticed recently my push notifications on my iPhone is no longer being delivered as quickly from my iPhone compared to my wife’s iPhone. There’s consistently about a 30 second delay between the two devices. I’ve tried reseting the Push ID, resetting the device from the app, rebooting the phone, and even deleting and re-installing the app, but the issue persists.

Any ideas?
