Hey Gonsolo,
It’s a pleasant to e-meet you.
My name is Guy and I’ll do my best to promote your issue.
We will probably need more information in order to make sure this issue is assigned to the relevant engineer at Intel,
To make sure your issue gets the proper attention and prioritized accordingly – I would kindly ask you to report it via Intel Customer Support service which can be found here: https://www.intel.com/content/www/us/en/support/contact-support.html?productId=59484,59485,83418#@11
Give me a ping once the request has been opened and I'll do my best to track it and make sure it will land in the right hands.
Thanks,
Guy.
