Troubleshooting Kindle 4 sync issue

[byelims]

Hello. Recently I made a mobi e-book by myself. Yesterday, I realized that even self-made mobi can sync the furthest location between devices with ASIN. So I add it manually and it works well on PC & Android. But the sync option is gray on Kindle 4. I tried to open an Amazon-sold book, it is OK.

So do you have this problem on Kindle 4? Whether it still works on Kindle 3? Or maybe I made some mistakes on the mobi?

It needs to be emailed to your Kindle so it's part of the Personal documents cloud then it will work.

Thanks for your reply. I have tried as what you said, but the Presonal Documents only sync between Kindle Devices. Kindle Devices can't read the location on PC & Android, and vice versa.

I just found how to fix the issue. I didn't add EXTH record 501. Thank DiapDealer.
