Bridge locked grid view showing all photos on a single line as compared previous version

[AussieChic]

Can anyone assist with how to see the whole grid in the updated 2023 Bridge please? 

Before updating, I could see the complete grid and easily scroll down through them which is very important with folders of large number of photos

Now, I have one single line of photos and can't see how to change this.

Looking forward to stepped advice.  Many thanks
