Hello @Bobojo and Welcome(!) to the forums. Your Ionic will show this screen if you type the password wrong exactly 10 times since the time when you last unlocked it. The Lock resets every 24 hours or whenever you take the Ionic off. To unlock it you have to open the Fitbit app, head to the Ionic settings, scroll down to device lock, enter your password, Then you have to change the password to something other than your current one. You can always change the password back by following the aforementioned steps.
Good Luck!
