I'm not liking mobi. So I tried to change preferred output format to azw3, but still mobi is created cause periodicals support only mobi.
So instead I've selected epub as output and then convert it to azw3. (kfx output does something similar, azw3 conversion doesn't take much time unlike kfx.)
https://www.mobileread.com/forums/sh...d.php?t=319765 I came across this post, but my news source doesn't have svg images like it says.
device doesn't hang but it just wont allow me to go back to home/library, like you can see from spoiler image.. the whole menu is blacked(white) out. I have to connect the device to pc and remove the azw3 to get to home. This problem occurs only with calibre fetched periodicals. With normal epub books converted to azw3, device doesn't show this problem.
