The TrackR "Find My Phone" skill is witnessing a bug on phones running iOS versions 11.0.0 to 11.0.3. The bug consists of asking Alexa to ring your phone, but the phone will not ring. To fix the issue, please update to iOS 11.1 which is available now. You can see how to update your phone's iOS version by clicking here. Please contact us if you have any questions via the chat widget in the bottom right hand corner of the screen or via e-mail at firstname.lastname@example.org. Thank you!
