Calendar Alert "Time to Leave" is stuck on Walking time

Hey there Jeeper83,

Have you tried changing the travel method since noticing it only showing walking time? If not, give this a try next and check to see if the issue persists. To change travel method, use the steps below after opening the Maps app:

1. Do one of the following:

• Say something like “Hey Siri, give me transit directions to the Ferry Building.” Learn how to ask Siri.

Note: Siri transit directions aren’t available in all countries or regions.

• Tap your destination (such as a search result in Maps or a landmark on a map), or touch and hold anywhere on the map, then tap the directions button.

2. When a suggested route appears, you can do any of the following:

Switch to transit directions: If transit isn’t your default mode of travel, tap  to see a suggested transit route.

Choose a future departure or arrival time: Tap Leaving Now (near the top of the route card), select a time or date for departure or arrival, then tap Done.

Select which transit method you prefer: Scroll to the bottom of the route card, then select your preferences.

Take care!
