Hello @Julieking, nice to see you have joined to our Fitbit Community! I'm wondering when you refer to your Blaze is not updating, are you referring to a firmware update or your data is not syncing with the Fitbit app?
I'm assuming you are experiencing the latter, but feel free to correct me and provide me more details if I'm wrong. But if this is related to the syncing process, the following post might give you some extra help: Having trouble syncing? (here's how to fix this).
See you later and hope this helps.
