I just noticed I can no longer send or receive attachments over wifi since I installed Sense Six. It only works over data connection. Anyone else experiencing this or have a fix?
I know this thread has gone stale, but if anyone is still listening, try this:
Go to data usage, menu, 'hotspots'. Make sure that your trusted networks are not marked as hotspots. This fixed a G+ photo backup issue for me and the issues here sound similar (certain apps won't move data over wifi). Which is what the hotspot setting is meant to control.
