iAP2 IdentificationInformation Rejected - Product Plan Status Question

Hello,

We are developing an iAP2 accessory and encountering an issue during the Identification phase.

Issue:

• Authentication: ✅ Successful
• Identification: ❌ IdentificationInformation rejected (0x1D03)
• Product Plan Status: "Submitted" (in MFi Portal)

What we've verified:

1. ProductPlanUID matches MFi Portal
2. All required parameters per R43 Table 101-9 are included
3. Parameters are in ascending order by ID
4. Message format appears correct

Observation: iPhone accepts the message format but still rejects IdentificationInformation, suggesting the issue may be related to Product Plan configuration or status rather than parameter format.

Questions:

1. Can a Product Plan with status "Submitted" complete iAP2 identification, or does it need to be "Approved"?
2. Are there any Product Plan configuration requirements that might not be visible in MFi Portal?
3. Should we configure "Control Message Lists" in Product Plan? (We don't see this option in Portal)

We can provide additional technical details through secure channels if needed.

Thank you for your assistance.
