I do not think, it makes much difference whether you are using Android or iOS. The car location and trip info is uploaded to Toyota's servers through the car's inbuilt connection/GPS. Then the app just downloads the data from the servers. You can see the same info using MyT via a web browser. Of course, if you are sending preplanned trips to your car's navigation system, then it can be dependent on the app and OS.
There have been some occasions for me, where the trip data is missing completely or appears only after a few hours. Also the location data is usually lagging behind in these situations.
I suppose that hybrid score saying "Not applicable for this trip" is normal, if you drive only for a very short distance. There's not enough driving data to calculate a meaningful score.
