Critical Bug — Cannot Submit or Delete Draft Response to Guideline 5.6.4 Notice — App at Risk of Removal

Hi everyone, I am hoping someone here has experienced this and can help, because we are in a really difficult position right now. We received a notice from App Review regarding Guideline 5.6.4 and have been working hard to prepare a full response with supporting evidence. The problem is that a draft response exists in App Store Connect that we cannot submit or delete. Every time we click either Submit or Delete Draft, we get the same error: "The resource cannot be found" That is it. No further explanation, no workaround, nothing. The draft is just stuck there and we cannot get past it. Because we could not submit through the normal channel, we uploaded a new build with our action plan included in the notes, hoping that would reach the review team. The build has been sitting there unreviewed. We have raised a support ticket with Apple Developer Support and have not received any response. The clock is ticking. App Review has given us a deadline to respond or face removal from the App Store. We have our response ready. We have our evidence ready. We just physically cannot submit it because of what appears to be a technical bug on Apple's side. Has anyone else hit this "resource cannot be found" error on a draft App Review response? Is there any other channel we can use to get this in front of the App Review team directly? We have tried everything we can think of. Any help would be massively appreciated. This is our livelihood and the deadline pressure combined with a broken system is genuinely distressing. Thank you
