Ps4 BF4 multiplayer problems

Hi,

I have the following problems with Bf4 on PS4:

- When I am in the server browser menu I can't find or see any servers. No matter what kind of filter has been selected. This happens every time.

-When I try to join a random gamemode in multiplayer, 80% of the time there comes a message 'Lost connection to server.' or something like that.

-All the unlocks are marked with an orange triangle, then if you look at the unlock, the orange triangle disappears. It's already the 4th time that ALL my unlocks are again marked with this triangle, even after looking at them. So normally I have no orange triangles because I look at every unlock.

- I read on the net that there is a major problem with the 'netcode' of the game. I've had problems with having no hitmarkers, doing 0 damage when shooting directly at an enemy from close range, getting killed from behind a corner, etc. Of course I don't really know what the netcode is or that it is even true, but maybe someone here can tell me more about it.

-2 Times already I've had an error during gaming in mulyiplayer and had to close the application. This happened for no reason, just all of a sudden the game stops and the error appears. 

These are some of the problems I've had and still have.

Are there more cases like this or is this a known issue? 

Is it possible to hear from the developers?

When is this going to be fixed?

Thank you.

Greetz!
