Oh my @jdadddd you say it is spinning, but at what step of the setup process is this.
I'm going to assume that the spinning is not on the Ionic, but I don't. See any mention of what device this spinning is on?
On Android I would Kill the Fitbit App, open the app and try again
Or you trying to set the Ionic up like the title says?
Mentioning that you want to get sleep back it makes me think that the tracker has already been setup and it is a sync problem. If this is the case I hope that the tracker was not removed from the app
Once the tracker syncs Fitbit will be able to determine your sleep.
Why won't my Fitbit device sync?
