It did update on the first time I turned it on to 3.11. I think I am just going to leave it as it is. I got used to it now. I just removed all the margins (top and bottom) so now it nicely uses whole screen.
One thing that is a bit bothering are the organised lists <ol> the numbers on my Aura appear skewed. Not like italic just like the left side of the number is pulled down a bit it makes look them broken. This is the case with all font types even with Arial I uploaded myself onto the kobo. Has anyone noticed this?
