BF4 PS3 to PS4 China Rising digital pre order DLC missing

Ive been attempting to play my BF4 China Rising Xpack on my PS4 since Xmas morning. Ive read thru I believe to be every single forum on the net! There are a few problems that are linked to not being able to play your China Rising Xpack. The first two are posted all over the net on almost every site/forum there is. One being that the "price" when you attempt to DL the xpack either from the in game menus or the PSN Store youre prompted to buy it for $14.99. The $14.99 price box is in fact clickable and is a drop down menu. Simply click the box and click on the "FREE" price rather than the 14.99 price. The second well published issue is that your Soldier in your Battlelog (from the battlelog webpage/I accessed mine via PC) must match the account you're attempting to play the Xpack on. When I went to my soldier on my battlelog(www.battlelog.battlefield.com) it was a different "account" than the account I was attempting to play on. When I clicked on my soldier there was in fact FOUR soldiers that popped up under the drop down menu. One was mine from BF3 on PS3 and two were from my little brothers account. One being his current BF4/PS4 account and his other being a BF3/PS3 account. The soldier that was active was one of my little brothers from BF3/PS3. So I simply clicked my BF4/PS4 soldier and activated him. I still couldn't log in though. Even though my PS4 showed China Rising being Downloaded and Installed. So I found last night a thread on some website that I cant even remember. It stated for the first time a third problem that was incredibly fixable which isn't showing up on any of the major threads/forums/websites. So I posted it here on Battlelog hoping to help as many gamers as I can that are as frustrated as I was. So...you simply go into your settings on your PS4, click on PSN, than click on "RESTORE LICENSES"...that's (Settings-->PSN-->Restore Licenses). BAM! takes about 5 seconds flat and WHAM-O! Im rocking and rolling in China Rising getting my face melted off because I don't know the new maps yet =P. I hope this helps my fellow PS4 gamers! Cya in China! PS. Must be a known step considering its built right into the PS4. Any future DLC not playing problems I have I will now remember to "Restore Licenses" from the PS4 dashboard first!
