Do you really mean your Charge 2 tracker has stopped showing sleep data, or do you mean your phone app has stopped showing sleep data?
Best AnswerGlomming on to this post. I saw my sleep data first thing this morning, now it’s disappeared. Restarted fitbit many times as well as my phone
Best AnswerIf you'd like to restore a sleep log you have recently deleted, please tap on the Sleep Tile in the Fitbit app, then on the plus (+) sign on the top right corner of the screen, and finally on Add Sleep Log.
Regards,
Will
