Unusable. Here I thought the myChevy app for my Chevy volt was terrible. Then I go and buy a 2022 Toyota RAV4 Prime and download the Toyota app. Talk about useless! It allowed me to associate my vehicle via VIN easily enough, but provides no functionality. When I open the app, it SOMETIMES appears to show me my mileage and fuel gauge (both of which are stale data), but doesn't provide me with a remote start or any useful interface. Usually the app just appears to freeze / spin indefinitely.
