The service does support and automatically converts it into the required format. The kindle itself doesn’t

Yeah, I like to keep the usb as the last resort because I have to open my bulky computer, connect my dangling micro usb cable and shit like that

The issue is solved now. You can see the other comment. It was some kind of EPUB internal format error

Can confirm, it worked! Although I don’t understand the niche technicalities myself

There’s always someone on the internet who has had the issue. I will mark this as solved. Thanks for your time!

I have heard about this calibre thing. Never tried because it’s such a hassle to go physical with the cables and shit. Seems like there’s no other way rn. Thanks

I tried it before, but it didn’t work. Didn’t knew you had to convert into mobi. Sweet. Thanks

I really really hate the polarised politics, Elon Musk hatred and web integrity thing that gets showered here day in and day out. Honestly I’m tired of blocking the communities and users of that type
