It's genuinely too difficult for most developers.

It may sound smug but I spent a lot of time trying to understand how to sync things offline. I'm not saying I am incredibly talented, just that I put in the hard work here.

It's very, very obvious to me that a lot of people in the space just aren't willing to do that. To be frank it's obvious in a few of these posts.

So yeah, it takes a bit of effort. If you don't want to genuinely learn some new shit, dig into the papers, be confused - it's probably not for you.
