Newbie Question: Layers in Layout?

I am not sure what I did in Layout but I tried assigning layers to my document and now it seems the document pages are “stuck” on one scene. I didn’t think to “undo” my move and thought I would save it and work on it at a later time, but it is now that later time and I am still lost.
Is there a link to a tutorial that I haven’t found?

It kind of sounds like you made a layer “shared” that you shouldn’t have. How about uploading the LayOut file so we can see what you did. It’ll be much easier to answer you correctly that way.
