Seedance not working anymore when using references

Since this morning, Seedance 2.0 models (normal and fast) seems to have stopped working when using image references.

Pure text-to-video generation works. However, the issue occurs as soon as external media is uploaded to be used as a reference (or as initial/final frame). Shortly after starting the generation, it fails and displays an error message stating: "The model you are using is currently unavailable, please try again later."

This issue has been persisting all day.
It has been confirmed by colleagues in my studio, as well as by several other users in the Firefly Discord community.
It seems this might be related to a model routing bug. If I try to relaunch previously successful Seedance generations (that include references) from the Firefly iOS app, I receive a completely different error message about a model being unavailable, specifically referring to "Gemini 3.1 flash lite."
