I tried using the &ttype=arr&date=11/30&time=12:00
Like I have found online, but this doesn't work unfortunately.
comgooglemaps://?daddr=DESTINATION&saddr=FROMADDRESS&directionsmode=transit&ttype=arr&time=12%3A00&date=11%2F30
Opening the link with an iPhone opens the app. Unfortunately, it doesn't change the date & time of the itinerary.
Any ideas?
