On mac specifically, I have a library pulling from an iCloud folder. The files and thumbnails show up in the library, but when i double click on a volume it flashes a new screen for a split second and then I’m back at the library bookshelf view.
When I open from the same iCloud folder on iOS, they open just fine. They’re all .cbz files. I’ve tried removing and re-opening the library from that iCloud folder, with no luck.
