Have to update a lot

A powerful app with fast connectivity. The only major problem is even there’s a new version available, it doesn’t automatically update so you have to delete the app and reinstall periodically. New accessories and ECUs always require updating the app too.

AT中にも落ちるので早急に対策版をリリースして欲しい。
