Unable to Create Work Profile on Huawei MatePad Pro (HarmonyOS 4.3.0)

Hello Microsoft Support,

I’m unable to set up a work profile on my Huawei MatePad Pro (Model: WEB-W09, HarmonyOS 4.3.0) using the Intune Company Portal. When attempting to enroll, I receive the following errors:

1. "Unable to create work profile" (Company Portal)
2. "A work profile can't be added to this device" (Android Managed Provisioning)

Device Details:

• OS: HarmonyOS 4.3.0
• Model: HUAWEI MatePad Pro (WEB-W09)
• RAM: 12GB | Storage: 512GB
• Google Services Status: Installed via third-party (GBox) – Google Play & GMS are functioning normally, but native Huawei Mobile Services (HMS) is also present.

What I’ve Tried:

• Ensured the device meets minimum requirements.
• Verified no pending OS updates.
• Confirmed Google Play Services are operational (via GBox).

Request:

1. Could you confirm if work profiles are supported on HarmonyOS devices, even with Google Mobile Services (GMS) enabled via third-party methods?
2. If work profiles are not supported, are there alternative enrollment methods (e.g., MAM app protection without a work profile)?
3. Does Microsoft Intune officially support Huawei devices with HMS + sideloaded GMS?

Attached are screenshots of the errors and device details for reference.

Thank you for your assistance!
