@Jason_Silva @Beavis97 @slightly99 awesome, thanks! You guys are all enabled for beta firmware.
To grab the latest beta firmware, simply head to the Settings tab in your mobile app, then tap "Update Firmware" (ignore any messages about being on the latest firmware). You may need to tap "Update" on the following step more than once to trigger the update.
After an update and some refreshes to the lock (disconnect/reconnect, restart your app), you should see the version number on the settings page update to 1479336801.
We've also successfully tested downgrading to the production build in case you run into any unexpected issues.
