i dont get the unlocks from the story

They REALLY need to fix this as this is content WE the players paid for, there is no way we are getting locked away from content we literally paid for, it's not only an easy fix but there is multiple ways to fix it. 

As I mentioned previously there is about 3 ways to just fix this issue and I bet it would take an intern or entry level dev to fix it just like with Team Fortress 2 having like one or three guys still working on patches and even bug fixes and these are: 

1. Fix the Battlelog website to actually register and sync with EA App and/or Steam to finally give the players their weapon and dog tags they unlock from the campaign and have them unlock on multiplayer

2. In case option #1 is too difficult by any number of reasons, EA can work on a small update making all of these weapons to be already unlocked for the players since level 1, that way players will still have access to the content they paid for  and they will not have to mess around with much elements in the game server side. 

3. This option is the most logical sort of say and is similar to option #2 and that is to update the game and server side to have these weapons included on the unlock pool of the numerous weapons in the multiplayer that are unlock by earning score with the same weapon class, this not only makes a good substitute way to access this content the players already paid for but it also feeds into one of the core parts of the gameplay and that is progressing and grinding for unlocks, of course since these were supposed to be unlocked from the campaign the devs could put a number of points to be earned around the middle of the unlock pool so it's not so easy to unlock but not too hard and time consuming to unlock such as the last unlockable weapons available this method. 

Keep in mind to whoever is reading this that EA has already set a precedent they are willing and will update older titles by adding to BF1 an anti cheat system years after it's last big update and with two other newer games already released (BFV and BF2042 with BFV also getting the anti cheat update years after it's last update). So they have NO excuse to fix this, therefore they must also fix this issue too and this is a far easier issue to resolved than implementing a whole anti cheat into a game years after the last big update for BF1.

My apologies if I sound a bit rude, that's not my intention but this is not a question of "if" this is something that must be fixed as I'll keep saying it as many times as it is needed but this is content that was paid for, there was no notice giving a fair warning  to the players that the assignments of campaign would be glitch out giving them enough time to just complete it before it glitches and there is currently NO substitue way to get these weapons which there should be if option #1 of fixing this issue is not possible.
