What am I doing wrong? I just purchased and installed Affinity Publisher 1.7.3. I exported an important InDesign CS6 file as an idml file. When I try to Open it, the document is grayed out and will not open it. When I drag and drop it, I get a not compatible error message. What am I doing wrong? The whole purpose of purchasing Publisher this morning was to be able to convert my InDesign CS6 documents into something usable so that I can get rid of InDesign and upgrade my MacBook Pro to Catalina. Please help!
