Battlefield 1 Freunde einladen und Party-Funktion

Hello everyone, 

I love Battlefield 1, but the party "function" on the PC is getting on my last nerve, because it doesn't work at all. Not for me, and not for all my friends. Creating a party together is usually not possible, either nothing happens or an error code appears (usually something like EC:10200). 

Even if you do end up in a party together, you can see that the party leader has joined a game, but when you confirm, either nothing happens or you get an error code. At the moment, playing together is only possible with difficulty via serverbrowser. Surely there must be a fix for this?
