Sora-2 extensions stuck in processing?

Hello,

Tried to use the new Sora-2 API features, but video extension seems to get stuck in the processing state. Anyone got the same issue by any chance? Or is it even a know issue

Also, seems like the 20seconds parameter is not available when extending, we are still stuck with the 4-8-12seconds from the base generation settings. Is the documentation in advance compared to what was implemented?

Thanks!

After more investigation, it seems like the video.completed event is not getting sent when extending videos. Could someone confirm?
