Request for Tizen Partner Certificate (.p12)

I am currently developing a Tizen application for Samsung Smart TVs (HG43BU800EE) that requires advanced features such as:

To proceed with testing and deployment, I think I need access to a Tizen Partner Certificate (.p12).

I tested my application with a developer certificate by entering the DUID, and it works. However, since we are interested in deploying our IPTV system on multiple TVs at the same time, including in hotels and hospitals, I need this certificate. Who can help me?
Thanks in advance,
Valentin

Hello,

For the past two weeks, I have been trying to open a ticket via Seller2.0, but unfortunately, I have not been able to submit my message. I am always stuck at step 4: Select App.

This is why I have tried to contact you through another channel. I don’t understand why it is so difficult to get a response from you.
