This is new, within the last few months. Previously I have had no problem, and I have no idea what is different. I have read many threads about related problems and tried many things. This is affecting all PDFs, at least all of them that I have tried (which is, probably, in the hundreds).
Thanks, that has been my standard practice, and it has stopped working. in particular, i can enter something into the author box, but it won’t stick. even if i update the database records, it doesn’t stick
on MacOS Big Sur, I followed the devonthink UG and went in and changed the forced edit preference for PDF. also on finder i made sure files were not locked.
