DSA trader verification entry unavailable for China Mainland developer using KiezelPay

Hello Connect IQ team,

I am preparing Kitten Knight, a watch face with a 72-hour trial and an optional USD 4.99 unlock through KiezelPay. My developer display name is KittenKnightStudio. The production app has not been submitted or published; I would like to complete the required trader verification first.

While signed in, https://apps.garmin.com/dsa shows "The page you are looking for was not found". The same path on apps-developer.garmin.com also failed when checked. I did not see a separate Account Checkup or verification-completed status on the developer dashboard.

The Merchant Account setup appears to be for Garmin native payments, and its Country of Operation list does not include China Mainland, where I operate. I do not want to select an incorrect country or register for the wrong payment system.

Garmin Connect Developer Program Support has advised me to ask in this forum because its contact form only covers API-related incidents.

Could the Connect IQ team please confirm:
1. The current trader-verification entry point for a China Mainland developer using third-party payments such as KiezelPay.
2. Whether verification can be started before submitting a production app, and how to enable Account Checkup for this account.
3. Whether any Garmin native merchant enrollment is required when the app uses only KiezelPay.
4. Which secure portal should be used for identity/address verification, and which document types/languages are accepted.

I will provide any required identity documents only through the official secure verification process, not in a public post.

Thank you for your guidance.
