Autel recommends putting the .bin file on the sd card in the drone to update the firmware. Mine updated the firmware and auto updated the app. Took about 8 minutes or so.My best guess is that they intend to match the google playstore version with the ios appstore version number. You can sideload the android app now if you want. It'll prompt you to update the evo II firmware when you connect or you can use the .bin file to update.
Ok many thanksOne version is for general release and the other version is beta
