Hello,
my public library finally enables us to borrow e-books (in .epub format), but I cannot change font type and font size, nor increase line space on those books. For my own books, I know how to make a copy and delete the .css file in Sigil if the font will not change, but with public library books I cannot do that due to DRM protection. The public library says this is the fault of Kobo, because it cannot override the built-in css file from public library books, as apparently (?) other e-readers used for library books can.
There was an old topic discussing Kobo epub fixer app, but those links are dead and I cannot find that app anywhere. Some say that Kobo firmware has fixed this issue, but this is not true - I have the latest software installed, I have just synced my Kobo Aura One and nothing happens.
What can I do to increase font size, change font and increase line space in library books? I am far-sighted and the small font is killing my eyes, I cannot read library books at all without adjusting the font to my preference.
Cheers for any tips on how to solve this.
