This is a pretty niche problem, I imagine, but it's hopefully worth reporting. I use a pretty old tablet (a 10-year-old third-gen iPad) to read on, most of the time, and yesterday morning, it worked fine. Yesterday evening, not so much. I can see the cover/preview image for a series, and the thumbnails for associated images, but if I open a chapter or click on a thumbnail, I just get a blank box with a page number like "1" or an image id like "namename1207-img." I know losing compatibility comes with using ancient tech, but I'm hoping this won't be a permanent sadness.
