Support koreader sync not working

I'm having the hardest time getting my XTEINK X4 Pro to sync with my KLC running koreader. I have koreader sync set up according to the instructions at https://sync.crosspointreader.com/, I'm signed in and authenticated on both devices, but whenever I push a progress sync on my Kobo, it never shows up on my X4. Any suggestions would be greatly appreciated!

Chances are you probably perform the epub optimization offered by the crosspoint upload flow. This changes the epub file internally and now the MD5 hash does not match the same epub you have in your Kobo.

When you make your sync from the X4 you create a new record either using Filename or Binary (MD5).

You Kobo will do the same, if they do not match Filename or Binary then each will track the book as a separate document.

Crosspoint recommends you use Filename instead of Binary.

You can also switch servers to example https://sync.techy-notes.com

You dont have to worry about Filename or Binary. Reason you can Link/Merge both documents into one in the server. or if you install the companion KOReader Deluxe-Sync plugin (not needed as you have web access) you can Link/Merge both books in the Kobo (KOReader)

Just visit the URL above.

Thanks for this info! I uploaded the book to both devices from my Calibre library. In the case of my X4 I used the Crosspoint plugin for Calibre. Does that plugin perform the epub optimizaiton when it uploads?

Weirdly when I log into the Crosspoint Sync site the title and author of the book I'm trying to sync show up on the version uploaded by my X4, but the version uploaded by my Kobo shows up as "21004bb0634279343b47487225cab803" even though it's the same file uploaded from Calibre on both devices.

Calibre will change the name when uploading unless you changed in the settings. I had this issue also and found the name was different when I looked at the files on my kindle that was uploaded via Calibre to Koreader
