wiige We have checked to see why the link is not being added properly, and it appears to be due to a change in the translation of "Previous:" and "Next:" on the Chinese page. Other documents in Chinese (e.g., general runtime guide and user guide) use "下一节: / 上一节:" , but the spine-unity runtime documentation uses "下一章: / 上一章:" , which seems to be causing the detection to fail.
If there is no particular reason why this should be the case, I would like to use "下一节: / 上一节:" to match the other documents. Do you think we should use "下一章: / 上一章:", including the other pages? Let me know your opinion!
