This is a really interesting project. Having offline access to Wikipedia can be especially useful in places where internet connectivity is limited. I like the idea of keeping knowledge accessible without depending on a constant connection

Are you getting a blank page in the Kiwix app? Same here.

Give this a try https://browse.library.kiwix.org/#lang=eng

I download with a browser or as a torrent. I then copy it to my tablet's storage card.

Kiwix dumps of Wikimedia wikis, including Wikipedia, are available here: https://dumps.wikimedia.org/other/kiwix/zim/

You may also want to check if one of the mirrors has a copy; it might download faster.

On the left side of the window you can switch to "Online Files". By default it is set to "Local Files", I think. Maybe that's the "issue"?
