When a new update is released, we will push it to the Play Store. Every time you connect your tablet to the internet, it should check for available app updates. If a new version of the Ditch Assist app is available it should be downloaded automatically. If you don't have automatic updates turned on then you'll need to navigate to the Play Store and install the update manually.
After any app updates please double check your settings. Some of the settings for GPS antenna height etc may have been reset.
