I used this calibre extension(Releases · crosspoint-reader/calibre-plugins) to upload my books to my X4. Koreader Sync works just fine between books I've sent to my jailbroken kindle 11th paperwhite signature edition and my zfold4 via calibre wirelessly(connect/share) but it doesn't seem to work at all with my X4. I updated my X4 to the newest version of Crosspoint 1.3 and decided to try putting a book directly on its microsd and inserting a book on my phone's Koreader without Calibre and it just worked. Did i mess up somewhere with Calibre? Is there something I can do to avoid having to remove my microsd whenever I need to add new books?

I purchased my Xteink X4 back on the 24th of april and it arrived on May 13th. It is working just fine, and since I bought it before they started locking the devices down I had no trouble installing crosspoint. I alrrady have a Kindle Paperwhite signature edition 11th edition (I jailbroke it last year) and a Galaxy fold 4, but when I came across a video of a doctor showing the xteink x4 fitting inside their scrubs I just couldn't not buy it. I'm from Brazil and currently halfway through medschool. being able to carry a book on my scrubs and or whitecoat in between meeting patients is great
