Jim - sorry, I occasionally think out loud online & need to work on that. I was referring to some warning about potential compatibility with Catalina when purchasing, but no big deal. I’ve had DTP for a long time and am only now getting serious about using it. I’m sure any Catalina glitches will get sorted out in due course, and am enthused about DTP capabilities. I currently have it sync with iCloud, but I too will just stick to the Mac until it gets resolved.
