I'm using iPad Safari 9.x, I know it's not supported but it works fine, except for some chapters where it behaves in a weird way. I tried debugging it quickly but couldn't find anything obviously broken and I don't see differences between the chapters that do work and those that don't.
For example, Sousou no Frieren
chapter 6 doesn't work but
chapter 12 does.
This is what happens on chapters that don't work:
[ul]
[*]preloading doesn't work
[*]when switching to a page that I haven't loaded before (page 1 -> page 2), it gets stuck on the loading animation indefinitely
[*]if I switch to another page and then go back to it (page 2 -> page 3 -> page 2), it shows the page (provided the image has already loaded)
[/ul]
Do you have any idea about what could be causing this? I'd very much like to keep reading manga on this ipad so I can look into it myself.
