Drawing mode is not working as expected

Hi,

We are trying to create a drawing board in scene1. After we draw a sketch in drawing board and move to another scene and come back to scene1, We lost everything drawn on the drawing board. Is there a way to retain the drawing. Attaching the file for the reference. Drawing.zip (6.2 MB)

Hello! Would you mind opening a Support Ticket to discuss this issue?

Thanks!
