Hey everyone, good news for those who asked: Apple finally approved the updated forms, and Sutra (my iOS reader for Calibre, Kavita and other OPDS feeds) is officially back in the European App Store!

Sneak Peek: CBZ & Smart Panel Support
I’m currently deep in the weeds building panel-by-panel comic support. As you can see in the attached comparison image, tapping the bottom-right icon isolates individual panels to fit your screen natively, making reading on smaller devices dramatically better.

Comics have wildly different panel definitions and chromas, so getting this consistent across my test bench is taking up all my free time outside of my day job and family. Because this is the core feature of the next update, I want it to be close to perfect before shipping - so the release may slip to next week.

Thanks to everyone using the app, and do let me know if you have any feedback on the preview!

I got a new kindle and I needed it on a new account. I was wondering if there is a way to use Calibre to transfer from on Kindle to another. Just under different accounts. And if there is a way to do it, how would you go about it?

Yesterday I put a bunch of books on my Kobo. Last night I went to read and none of the books show up. Today I went back to Calibre to see what's going on, and I got the above error message. The books do show when I look at my Kobo on the computer, but I can't find them anywhere on my device.

I don't know what that error means--it was fine yesterday. I don't know where to go from here, and the help Kobo is offering is only for books I purchased or borrowed from them. I did a sync and repair on the Kobo. Where do I go from here?

When I edit the metadata for a Kindle book (e.g., cover or author name) that is already loaded onto my Kindle Paperwhite 11th generation and then send the edited version to my Kindle, I always end up with both the original and the edited versions. I can't find a way to delete the original off my Kindle other than permanently deleting it from my Amazon content. I see many suggestions in other posts to use a filter to show just the new one, but has anyone found a way to remove the older version other than permanently deleting?

Hello, I'm for some reason not able to convert a KFX file (definitely DRM-free, I have both related plug ins) to EPUB. I'm encountering the following error:

ERROR: KFX conversion failed: <p><b>Cannot convert [name of the book] </b><br/><br/>KeyError('YJFragmentList item is missing: c0:: $260::')</p>

Following advice in a similar Reddit post, I've also tried converting via KCC, but it doesn't seem to work either. What do I do? Thanks in advance for any help!

I'm currently using version 2.4.0 of Kindle, but this version doesn't allow me to download books so I can later extract them using Calibre. What is the latest version that allows me to download books and that the program can use to remove the DRM?

I have one book from on Kindle android and wanna get it in the form of pdf on my pc and store in my pendrive.

Year ago i tried one using Calibre using Dedrm android key or something i don't remember please help.

Today finally installed remanager and KoReader on my remarkable move. Everything seems ok, KoReader runs. But i can’t connect to calibre server. Yes the server run. I get a handshake error.

Calibre runs on my macbook Pro M1 both latest version.

somebody have a clue?

Even though all of my books are imported from Calibre to my Kobo Libra Colour, only about half of them are listed as such. I have tried deleting the books (and their respected folders) from the e-reader and then resending from Calibre but the issue persists. The book is sent to the e-reader and has a green check mark indicating that it is on the device, but upon ejecting and reestablishing the connection the book is no longer listed as onboard (even though it is). What am I overlooking?

I am running koreader with a few plugins, but I haven't had the issue with this setup previously.
