Unique Device ID help!

I am building an app where I want the UUID to remain the same even after the user uninstalls the app. I came across the Ionic Native plugin and when I implement the same usage code and try to run it on an iOS device, I see in the logs that the uuid is “null”. Is there anyone out there who has a working model or can help me with this? Thanks!

Probably a stupid question, but are you sure you’re waiting until the platform is ready before trying to interact with plugins?
