Switching account profile from old fitbit device to new different device

[MGrem]

I have a new Fitbit - inspire HR; my account is linked to old fitbit Charger - how do I set to new?

Assuming you want to keep your old data:

First sync from old tracker to be sure all data on it gets to Fitbit database.

Then, on phone app, tap profile pic near top left on 'Today' page; then on 'Account' page, tap picture of your old tracker;  then on tracker page, tap trash can icon near top right.  Then on phone, go to bluetooth settings to see if old tracker is still paired to phone;  if so, unpair it.

Then, in Fitbit app still logged into same Fitbit account/email, on 'Account' page tap 'Set up a Device' and follow instructions.

As long as you are in same account, data from new tracker will continue right along from other tracker's data.
