I installed the Automatic Pro in December 2016, have driven over 5000 miles in 448 trips since then and still have nothing showing in my insights drive style on the app. What's going on? Everything else appears to be working correctly from what I can tell.
It looks like there's an issue generating data for your specific vehicle. Your Subaru is less responsive than other vehicles in terms of consistently returning vehicle data used to generate the drive style insights (e.g. rpm, maf). In your car, the sample of rate of those fields is in the .25 - .33Hz range, while we're currently needing approx 1Hz to generate the insight.
All other features of Automatic should work fine, but we have work to do to handle vehicles like yours to generate the drive style insight.
