GE Smart Motion Plus Switch not being recognized

I’m trying to use the new Samsung SmartThings app on my iPhone for a newly installed GE z-wave smart motion plus switch and it says it doesn’t recognize it. I was able to add it to the SmartThings classic app and it works fine. Any ideas?

I have heard rumors the device does not pair well with the new app. @nathancu may have more info. However, you WILL need a custom DTH to run it in either environment to access both the switch and motion sensor. I have those in this thread:
