Did you work it out? Also, I can't see any of the attachments you all referenced, do I need to be using a browser as opposed to the Community app? So, my hangouts with that person is back to normal.
I know you might not be able to comment too specifically on this, but I hope that you guys seriously consider adding this in! I tried this both at and through gmail.
The available plugin is only for Windows computers, but sometimes people have issues trying to get it working.
I cleared the cache and date in the storage and I tried to log back into my Hangout with my gmail but still won't let me.
The grabby factor pisses me off more than anything else.
Google takes abuse of its services very seriously.
