I made changes in my SL project that you can see in SL preview but when I publish to Review 360 it is as if I didn't make those changes. Spelling errors that I fixed in SL do not show as fixed in Review360. Also, on some slides, the base layer doesn't go away so the text ends up overlapping between the layer and the base - but it looks fine in preview.
