[Q] MMS/APN Issues with CyanogenMod 11 topic

So ever since I did a wipe and flash last week of the CyanogenMod 11 nightly, I haven't been able to send/receive MMS messages. If someone sends me something, I'll get a message saying that they sent me something but it cannot be downloaded. From what I could tell, it could be my APN settings. I've tried a bunch of different things, the main two being what's shown on this webpage, and the following (default) settings:

Name: Verizon Internet
APN: VZWINTERNET
MCC: 311
MNC: 480
APN Type: default,dun,supl
APN protocol:: IPv4/IPv6
APN roaming protocol:: IPv4/IPv6

Now sometimes MMS will work, but take FOREVER to download. Other times, it just doesn't download. This is becoming really frustrating since I use group messages a lot to keep in touch with distant friends.

Could someone be able to help me out and tell me what I'm missing? This is becoming a huge inconvenience. Any help would be much appreciated!
