@Russ I signed out/closed the app and then opened it up again. See the below screenshots of the developer mode enabled and add device page. Developer mode enabled: [image: 1710539333171-st1.jpg] Cannot see "My Testing Devices": [image: 1710539362098-st2.jpg] I appreciate your assistance. Thank you.

Update: For anybody on the Apple ecosystem, I just used a workaround to solve the iOS ST developer mode problem. I installed the Android Studio on my Mac and used it to emulate an Android phone. I then installed Smartthings on the emulated phone and was able to enter developer mode to link to TriggerCMD.
