I'm using: Publisher V 2.1.1
MacOS: MacBook Air M2, 2022, Ventura Version 13.4.1 (22F82)
The placed PDFs are all PDF/X3 files. The PDFs were created by myself in Acrobat as PDF/X3 files. PDF X3 is currently the best version for us to work with our printers. That's why we use PDF-X3 files.
There are two modes in Publisher: Transfer and Interpret. When interpreting, Publisher tries to "read" the PDF. And this often results in a lot of nonsense (fonts are not available and are then displayed incorrectly; vectors are displayed distorted, etc.). When interpreting, you cannot be sure that the PDF is 100% identical to the original. That's why I'm using the Transfer-Mode.
And by the way: I can't believe nobody has reported this bug yet: I can't move selected elements (text elements, graphic elements) in Publisher on Mac using the cursor keys on the keyboard. If I use the cursor keys (left, right, up and down arrows) on the keyboard, nothing happens. The item does not move. That was already in the very first V2.x version. In V1 this bug is not.
Actually, I am currently no longer working in the V2 version. I'm back to the V1 again. With the documents that I still had as a V1 version. For me, the V2 is so useless that I even briefly thought about InDesign again. Also the screen design is worse for me than in V1. Many functions are so nested and implemented in small parts that it is very difficult to use them (mouse-clicks). Example: Document Settings -> Dimensions -> The icon for concatenating width and height is a disaster for me. You have to click on it exactly. And it's so small...
Sorry for everything. But I had to get rid of my V2 disappointment.
