Sync option doesnt appear on folder menu

Hi Jaione,

Welcome to the Box Community!

May I know what is your permission to these folders? You must have Editor Access or higher to see the "sync" option in a shared folder.

For more details, please take a look at this KB article: https://support.box.com/hc/en-us/articles/360044196393-Marking-Content-for-Box-Sync 

Best,
