Dear LISA 2026 team, I attempted to submit my validation segmentations today at 2:30 PM (WEST), which corresponds to 1:30 PM (UTC). However, the submission platform indicated that the current date is outside the permitted submission period. According to the challenge information, the validation submission phase is scheduled to remain open until 23:59 UTC of today (2th July). I was wondering whether there may have been an issue with the submission system or if the validation phase has already been closed. I would appreciate any clarification you can provide. Thank you for your time and availability.

I found the answer to my question in the post “LISA 2026 Challenge Validation Phase and Short Paper Submission Deadline Extension.” This has been resolved.
Dear LISA 2026 Challenge organizers, I am currently able to submit to all tasks. Could you please confirm whether the validation phase has been extended? Best regards, P-MedAI team
Dear LISA 2026 Challenge participants, Thanks for reaching out. Please try again now. Best regards, The LISA 2026 Challenge Organizers
I am experiencing the same issue. It is still July 2 in UTC, but the platform shows the current date is outside the permitted submission period.
