Using Contact and Motion Sensors to Trigger Alexa Routines (DTH in post 97) (Official Amazon Feature)

I’m really confused, having gone through this and several other similar topics. I’m attempting to have Alexa announce when one of the Smartthings door sensors opens. The Smartthings skill is enabled on the Alexa app, and the door sensors show up in the device list on the Alexa app.

I then created a routine in Alexa to announce when the “test sensor has opened.” Alexa shows it is connected to the Smartthings skill, it recognizes when the sensor is opened, and is verified that the routine is enabled.

But there is no audio announcement. I can manually play the announcement from within the routine, and it plays successfully through the designated Echo device, but it will not play from the triggered sensor.

I’m obviously missing something but am unable to shift through and would greatly appreciate some simplified guidance. Thank you!
