InDesign and Illustrator Exporting PDFs as Illustrator Files but still with the .pdf sufix
Using OS Mojave, 10.14.6
When I try to open a pdf that I've just exported using illustrator or indesign, instead of opening the document in preview, it starts up Illustrator and opens it there as an Illustrator pdf. My documents are saved as a pdf, but only opens as an Illustrator file.
I do have Preview as my default option, the files are saved as .pdf but even the icon is like it is an illustrator file.
I've deleated and relinstalled both, illustrator + indesign. When I deleated Illustrator, my .pdfs exported from indesign did showed as pdf, but when I reinstalled illustrator the problem was back.
