Hi @Headchef.Yang , thanks for the clarification.
At the moment, Bika.ai doesn’t yet support real-time collaborative editing at the field level, so mechanisms like OPs or changesets aren’t in place. Because of this, field-level undo isn’t available right now.
This is a known limitation and has been recorded as a feature request. I’ve shared your feedback with the product team so it can be considered as we continue to evolve the editing experience.
Really appreciate you taking the time to explain the use case.
