I am having this same issue. When a page first loads the images are fine, but after a few moments of InDesign "reading" the files, they disappear and are replaced with a bunch of lined images. I also tried creating a PDF and was given the same error message about the files not being linked (though they are). I too found if I replaced/linked images individually they would then display correctly—even with scrolling—but I still got the same linking error message when I tried to create a pdf. I hope this can be fixed soon!
