Let me share one more tip regarding the new navigation.
While navigating the Bottom tabs the Explore icon (the first one) has an extra function. It also works as the Retur-to-the-map-button while you are in the Commute, Saved, Contribute, or Updates tabs.
Also, when looking at the map it toggles the Explore nearby-panel on and off near the bottom of your screen.
In this, the name Explore seems appropriate. When it functions as a Return-button it is not really the best and intuitive name.
It took me some time to figure this out.
I hope you found this new navigation tip helpful.
Cheers
