I have an iPad Air 2 and an iMac using SMS forwarding via my iPhone 6. I can send/receive standard text messages and MMS messages from my iMac to my non-iPhone buddies without issue. On my iPad, attempting to send a picture results in a "Cannot Send Message - MMS Messaging needs to be enabled to send this message" error. Note that I can *receive* MMS messages to my iPad. There is no toggle anywhere on a wifi-only iPad to enable this. Was this something overlooked with the Continuity features in iOS8/Yosemite? I'm convinced it is only because it works flawlessly from my iMac, and the message I'm receiving is simply a leftover dialogue from the iPad sharing an OS with the iPhone. So...am I missing something, or is this a bug?
