You may need to re-align your pages depending on whether you design them in a landscape or portrait orientation.
1. To change the alignment of pages log into the RvRapid portal and click on Viewer Settings along the top toolbar
2. Under Page Display Mode select the relevant alignment
3. Click Update Page Mode to save
For landscape pages you will want the first option, which centres the pages in a single spread
For portrait pages you will want the second option which displays a double page spread.
