If the app shows you a screen that says "This Chipolo has already an owner, do you want to take care of it?", please confirm if this Chipolo is yours and follow the onscreen tutorial. You will need to shake the Chipolo to confirm and connect it with your phone.
If you cannot pass this screen please follow the reset connection procedure and try it again. If the problem persists please contact our Technical Support team via chipolo.net/support or on top of this page and you will be helped further.
