Google temporarily disabled YouTube’s advanced captions without warning
Summary
Google has temporarily disabled YouTube’s advanced SRV3 captions due to a bug that could cause playback issues. The change affects creators who used SRV3 for detailed caption customization, may prevent uploading new SRV3 captions, and means existing captions may not display until the feature is restored. Google describes the outage as temporary and is working on a fix, with no timeline provided.
