Can't upload fbook rom Lightroom classic to Blurb

I’ve been trying to upload 2 different books to Blurb from Lightroom Classic with no success. I had successfully uploaded on e month ago so I know it’s possible. Same version of software -- the latest  There are no issues with length of book, photos or size of files, etc. So I’m baffled. I rebooted my google fiber and Netgear modems as well. I see there are reports of similar bugs  but no clear solution. Have asked Blurb in meantime. Any update on this kind of thing. Someone seemed to have gotten somewhere by telling Blurb and also allowing full disk access. Will look into that. Let me know how to do that! Think in Settings. Thanks. Mary - July 25, 2026
