So there's this weird thing happening: I exported a file to PDF with InDesign, then a few days later made some changes to the InDesign file and tried to export again.
Yet, when I check the 'new' PDF, it's identical to the previous version! As if I hadn't made any changes.
I've saved the InDesign file, duplicated it, renamed it, exported to PDF with different titles, tried to export with different resolutions, restarted InDesign, restarted my computer, made sure InDesign was updated to the latest version... and yet it constantly exports the file as if no changes had been made.
It never did that before.
