I am running into the exact same issue where the prompt to register the device for platform SSO is not appearing.
Device is in Business Manager via the Apple Configurator app (iPhone). It has been synced to Intune just fine. All other Intune settings and apps apply fine.
When I look at the user account I see Platform Single Sign-on showing the Entra ID account and method of Secure Enclave key as per the profile settings I've used.

I see registration listed with a green dot and "registered". I see under Tokens "SSO tokens present".

But nothing is happening to prompt logging in to the device using the Entra ID. My test user account can only log into the local user account (admin) created via the Automated Device Enrollment process.

I've checked the profile for any leading/trailing spaces in the Extension Identifier field and all others.

I don't know what else to do at this point.
