No WhatsApp connection on mobile data on CM 12.1 !!!SOLVED!!!

Hi,
I installed CM 12.1 (Version 10.31 nightly) on my D405. I´m not able to receive Whats App messages, also FB Messenger seems not to be connected. Opening a webpage in Chrome works fine.
When I´m connected to WIFI everything also works fine.
Is it a bug or do I need to change some settings??
Greetings

Its a bug, update and everything will be fine

Updates did not help / Still no connection with WhatsApp
Hi!
Unfortunately updating to the newest nightly did not help. My WhatsApp is still does not receive messages.
I tried the following things:
Downgrading back to stock KitKat, then Updating to CM12.1 --> problem remains
Changing APN from wap.vodafone.de to web.vodafone.de --> problem remains
Right now I installed CM 11. No problem with WLAN or Mobile Data. WhatsApp also works fine. But This is not a real solution.
Please help!!!

Problem persists!!
Please help, guys!
Right now I tried to go back to KitKat via flashing KDZ file. So the system should be completely stock.
After installing CM 12.1 I installed WhatsApp from Play Store as usual.
When I try to set up my WhatsApp account, while being connected to mobile data, the verification process fails.
Doing the same with WIFI connection works fine.
What am I doing wrong??

SOLVED!!!
SOLVED!!!
I deleted whole APN list. Then added just one APN provided by my carrier. After switching mobile data off and on again I was able to receive WhatsApp.
Peace!

Try flashing the Stock KitKat ROM. I don't know if it'll work or not but won't hurt to give a try. Good luck.

For the sim card, try settings > network > network operator.
Tap that it should scan for available networks and give you a list, choose your provider and should register.
I forget the exact location coz I'm running Los 16 and its configured differently.
I'm not sure about the Bluetooth and WiFi ?
