As mentioned above. We were supposed to submit it 2 hours before the deadline. However, as we forgot to process the copyright transfer, and we couldn't access (for some reason) the IEEE Copyright Transfer webpage for 3 hours. We acknowledge that we should have been more mindful of this and will be so in future submissions.
My co-author contacted the organizers without informing me. I also contacted the organizers separately about this issue. Does anyone have the same thing happen to them? I would like to know what happened. Were you still able to have your paper published?
Conference is in July. My co-author will present this paper, and they have already completed and paid their registration. We have also accomplished the copyright transfer and had the manuscript stamped by IEEE PDF eXpress. Just failed the final manuscript submission.
