I purchased flic in July 2016. I never really did anything with it except create an account. Now when I try to connect to it with my phone, it says "out of range." When I press the button for at least 7 seconds and press "download," it says "key not downloaded." I thought there was supposed to be a light when I pressed the button, but no light. I took the battery out and checked the battery and it still reads good. Any suggestions?
