id_token not unique across platforms?

We've implementing SIWA on iOS and a web application using Sign in with Apple JS. I've setup a service ID tied to the application ID and can succesfully get callbacks on both platforms. I'm noticing that the user id provided by the iOS app is different than the id provided by the web application.


We were expecting these to be different so we can store on our end and identify the user without having to use their email.

Any updates on this? I am having same issue.
