Hey @LisaHalverson!  Try this...

Once the file has been uploaded and you are still in the editing window, click on the link to the file and then click Link Options

Once the tray pops up on the right side of the window, select the options for Preview inline and  Expand View by Default.

 Once you save the page, the document should load on the page. (You will not see the inline preview in the editing window.)

Hope this helps!
