How to update fitbit versa 2?
If you want to update Fitbit Versa 2, the first thing you should do is reboot it to refresh its memory and all. Then, try updating it again and see if it works this time.
If it still doesn’t work, the issue might be with the connection between your tracker and your phone, if you’re trying to update it via the latter.
In this situation, switch off Bluetooth on your phone and then turn it back on, and then try to update the tracker once both devices are linked.
