Guessing from the local manga guide pdfs wont work, but it looks like epubs should. I’ve never tried those though… It may only read the images from the epub, if there are any.

I’ll throw my hat in the ring!

Odd… What are the files formatted as? All of mine are cbz’s.

That’s odd that it won’t work with Tachiyomi for you. I followed the Kavita guide to connect it to Tachiyomi and it works fine for me.

+1 for Kavita, though I don’t use it for reading. I use OPDS in Kavita to read books on my phone (using MoonReader+ on Android) and share books with family.
