The navigation bubble will help you find the house number of a stop quickly, without changing apps. It also allows you to change between apps quickly.
For now, the navigation bubble is only available on Android and not on iOS. Please also note that it is not supported on Xiaomi devices that run MIUI Android ROM.
Here's how you can enable the navigation bubble on your Android device:
Open ☰ Menu
Tap 'Settings' ⚙️
You'll find the navigation bubble under 'Navigation mode bubble'
Press the toggle to turn on or off.
