testing the smoke and co listener

Hi all,So I installed Nest Protects throughout my house and I have the ring smoke and CO listener. I attempted to set it up pushed the blue button ran the nest alarm in test mode for the smoke and co alarms and attempted to "finish testing" but it never finishes testing and continues to say I need to finish testing. What am I doing wrong?I attempted to ininstall and reinstall the listener to no availal and hit the test button on the listener placed in 3 inches from the smoke alarm and it never finishes its testing mode. Please help.Thank you
