Doesnt work for the Atla model

I used this app to find my missing One years ago. Didnt work well, but it did lead me to my device. Tried to use for my Alta, it could pick it up at all. I found it the old fashioned way, you know, digging through everything and found it myself. Tried to see if the app could "find it" while it was in my hand...still nothing.
