Second day playing, just realized that sometimes when leveling up item rewards keep disappearing from the inventory.
 
 
The solution is simple, if you look at the screenshot you can see a ‘Synchronizing’ message/alert. You just need to wait at this screen until it finish synchronizing to save your items. Then you can check the inventory and see your new rewards.
 
 
Have fun! <3
