InCopy is going SO slow it's greatly reduced our efficiency in editing magazine text. Every text box takes at least 1 whole minute to check in and out of, and even when I've opened the text box, it takes ages for me to move my cursor to make an edit. I can barely move my mouse without it freezing up. This is happening on all of our work computers and my laptop at home, so it's not an isolated issue. Also three of our computers are brand-new and those computers are also having the same issues with InCopy. This started happening after we updated to Mojave. We've updated our applications (InDesign & InCopy) to the latest versions as well.
Hello....since updating to Mojave we too are having issues with existing InDesign files and numerous crashes exporting new files.
One thing I have been told is to downgrade from Catalina to Mojave.
