Default Still having MMS problems in Google Hangouts

Running stock 4.4.2. I can send MMS messages, but never the first time. It just displays "retrying", also group messages seem to not work. I get messages from the individual person that say "press to download", which never works. I understand the new hangout updates were supposed to fix these problems, but I still have them. I've tried changing my APN settings but I hit save and they jusy disapear. Any assistance is greatly appreciated.

-Thanks in advance
