Just like Layout 2015, Layout 2017 (Mac) exports un-optimized PDFs, so I have to (usually) do the extra step of optimizing in Acrobat. Kind of nice to not have to do that. Example: PDF comes out at 49.6MB, when it should be 8 or 9 MB. Also, another weird thing I found is it doesn't matter what the JPEG compression is, the file size is always the same.
Anyone else experience this?
