I think you’re mixing up technology terms. The map shows directions but it doesn’t do navigation
Doing navigation in bubble through the browser will never yield consistent results
To properly do navigation or mimic navigation features, what in my opinion require a native app that can run in the background as the app is running. Current location information can be sent to bubble via a direct API connection
I will most likely work for the first few minutes, but the results are always going to be inconsistent and unreliable.
