Hi Nikita_Pere, have you already updated Lr Desktop to 5.6? We fixed a buch of sync issues within this version.
When you are already on 5.6...could you please send me a LR Desktop diagnostig log - best as a private message with a downloadable dropbox link.
You can trigger the log via LR Desktop preferences -> Lightroom Mobile and when you hold down the alt key you will notice a generate diagnostic log button
Thanks,
Guido
