The fit to width option is no longer working for me. I have tried it on an iphone and ipad. Both were updated to ios 27, so I’m guessing that is likely the problem.

I just tested this, and it's working fine on my end on ios 27. The fill mode currently uses the page dimensions metadata provided by the server, so it's possible that this metadata is missing for the book you're trying to read. In the next version, I'll add a local fallback so Komic can determine the page dimensions directly from the image when that metadata isn't available
