The channel above is sync’d with the web developers community who will review all suggestions, and reach out to reply, or ask further questions if they feel it’s needed.
If your suggestions are specific and technical you might find it more effective to post them directly in the related channel: security, app development, etc) where people will understand. That’s up to your judgement.
If your suggested change is about an improvement for a team, for example a new tool to help the media creation teams operations, then please get their views and feedback before suggesting our dev team build it. You can do this by posting in their teams channel on this forum. Then including a link to that discussion when posting in the ‘suggest improvement’ thread at the top of this post.
