Hi Parthiban,
On further validation, the document has a vertical direction texbox shape. Currently, document editor doesn’t provide support to vertical direction shape.
We have already logged this as feature request. We don’t have any immediate plans to implement this feature now.
We usually have an interval of at least three months between the releases. At the planning stage for every release cycle, we review all open features once again and finalize features for implementation based on specific parameters, including product vision, technological feasibility, and customer interest. The feedback will be moved to scheduled status with an estimated delivery period whenever we have more information to provide regarding the development of this improvement. We appreciate your patience until then.
