One of the nifty features of Google Calendar is that if you were to input an appointment along with the appointment’s location, Google will be able to calculate based on live traffic the best time for you to leave, ensuring that you will reach your meeting on time. It is a very handy feature to have, especially for those who are bad with time management.
Unfortunately according to Android Police, the feature isn’t working at the moment, or at least it doesn’t seem to be working for some users. As the report points out, users have been complaining about this issue dating back to November 2017 on the Google Product Forums, but so far it doesn’t seem like there is a fix for it.
Note that Recommended Departure times are still visible if users were to launch the Google app, where it will also display the upcoming event. However the issue is that the notifications about departure times are not coming through which means that if you don’t check the app, you might miss it completely.
