Can't send photos from this account - WTH? I have a Nexus 5 running 4.4.4.  I have a Google Apps account that I use for GMail, G+, etc.  My wife has a standard GMail account with G+ enabled.  We chat back and forth using the Hangouts feature rather than SMS as much as possible.  This works fine.  We can send each other photos through SMS, and it works fine.  

She can send me photos using the hangouts feature, and it works.  I cannot send her photos.  The message 


  Can't send photos from this account


Pops up at the top of the screen immediately.  Is this a feature I've disabled in my account somewhere?  How do I fix it?
The setting at the domain level was the issue.  I enabled it, and it starting working a few hours later. 

This shouldn't be an issue for standard Google accounts - just Google Apps accounts.
