iOS not downloading photo stream

[opinio]

I load photos into iPhoto on my Mac (drag them into photo stream) and it syncs the pics across my Mac iPhoto apps in photo stream and and also into Apple TV, but my iPhone and iPad no longer draw down new pics in photo stream. This has worked for me for a year or so but no longer do my iOS devices draw down new pics that I drop into iPhoto photo stream in OSX.

I have checked every setting in iOS I can think of.

Has Apple stopped this option with iOS photo stream? It suggests the iOS devices upload but perhaps no longer DL anymore.

Any other thoughts?
