When a software update is available, your Fusion 2 will automatically start downloading it the next time it syncs with the app. Your Fusion 2 will need enough battery to complete the update, so it's always a good idea to have the device plugged into charge before you attempt the update.
Make sure your phone/tablet is connected to a reliable internet connection as well.
If your update is having trouble completing, it is possible that your Fusion 2 has some stray files saved on it, causing the update to stall. But not to worry! There are a few things you can do to reformat your Fusion 2 to successfully accept the update.
First, force quit the app and do a factory reset on your Fusion 2 (instructions below). Make sure you have synced your current steps with the app, otherwise you will lose your current progress. You will then need to re-pair your device with the app. Once you do that, you should see the update prompt.
Factory reset: Double tap the Fusion 2 to turn on the screen, then swipe to the left of the time/date (and battery percentage) screen to select Apps > swipe to the second Apps screen to select settings > swipe to the factory reset screen and tap the check mark to confirm.
If factory resetting the Fusion 2 doesn't allow the update to go through, shoot us an email at email@example.com.
