A:Answer Hi, Temescal. Just a reminder that you can't connect multiple devices that use an app gallery to one account. For the Fitbit Charge series, Fitbit Ionic, Fitbit Inspire series, Fitbit Luxe, Fitbit Sense series, Fitbit Versa series, and Google Pixel Watch, only connect one of these devices to your account at a time. But since your Charge 2 does not have an app gallery, you can connect it to your account alongside your new Fitbit Versa 4.
