Finished calendar is to be in landscape mode, 11w x 8.5h. Printing firm's instructions are to separate facing-page spreads. Resulting PDF is in portrait mode as usual, but with alternating page orientations: even pages to left and odd pages facing right. Tried to compensate for this in inDesign by rotating even pages 180 degrees. That rotation did not "take", in that, after pressing 'OK" to accept rotated page, the page remained in its original (wrong) orientation.
Please show me how to fix this.
Set up as 8.5 x 11 portrait facing pages. Rotate each spread view 90 degrees clockwise.
