Nearby Zwifters toggle hangs if notifications active

Hi, I will describe an issue I’m in countering on the iPad in the companion app. I finally discovered that tapping the Nearby Zwifters header keeps me positioned in the middle of the screen. I’ve observed that during periods where many notifications come in if I perform this operation it no longer works. If I do nothing until all the notifications clear then all is well, but if I swipe away the notification and then double-tap the future no longer works. This is particularly aggravating when I am on a large group ride with heavy message traffic and it is rare that there is a period with no notifications.The only way I know to fix this is to kill the app and restart it.
