Move to Setup Assistant with Modern Authentication for Automated Device Enrollment

Copy paste but we have the exact issue and would like someone to reach out

@Intune_Support_Team , What is the plan to address the issue referenced? Per the guidance in this post, we have modified our enrollment process for ADE devices to use Setup Assistant with Modern Auth. The enrollment process was intuitive and did not require instructions beyond "follow the prompts". With the move to Setup Assistant with Modern Auth, the enrollment process is incredibly inconsistent due to Apple's setup process stepping in, and sometimes on top of, the MS enrollment process; thus requiring an IT resource to help new users set up the new device properly. The time it takes for the company portal app to install, configure itself, then check in, then download apps, then finally configure the apps (specifically authenticator) causes significant confusion oftentimes even when IT resources are involved. 

I understand that this may not have come on Microsoft's timeline, but in the meantime your users are suffering. Please help us.
