Re: Missing level up/unlock Rewards.

We are all having the issue, it’s a bug that came back  with the new  5.2 update. Ea is aware of the problem and will hopefully fix it with the upcoming 5.2 update improvements. 
topic for the update improvements and new ttk damages : https://answers.ea.com/t5/General-Discussion/Community-Broadcast-Improving-Update-5-2/m-p/8532090#M11336

also there is a topic with suggested solutions to unlock the missing content.

games -> bf5 -> bug reports -> 4. topic from the top 

(u can not miss it, it’s pinned to the top) 

I would recommend to just keep playing and wait for the update improvements.
