Firefly text-to-video (Sora 2) 12s videos: I keep getting “something went wrong, try later” errors. Credits are deducted even when no video is generated. Is this expected, or can credits be refunded? I’ve successfully generated 12s videos before.

They had not been restored and I bought some more credits. I had created a nearly 2 min video last week using Sora 2. I need 1 or 2 more 12 second pieces but it refuses to generate - getting the same message “something went wrong, try again later”. Used the same prompt I had used for my previous videos and the same message came up. Can you let me know what is going on? Have lost both time and money.
