???Where is the stage

I just started using Toon Boom Harmony Essentials but I have no idea where or how big the stage is. I’m looking at other’s animations and they seem to have a grey box showing where their stage is but when I open mine I can’t tell how large the stage is.

Is there a way I can tell where the stage is?

Thanks!

Would you upload the screen shot of your screen? I have never came across an issue like that.
Are you sure you are in Camera view instead of Drawing view?
