Thanks for the reference but I cannot find what I'm trying to do there...maybe I wasn't clear in my original post.
Say I have 10 collections in LR desktop. I want all of them on my iPad and only 2 on my iPhone. I can't see how to accomplish that. The sync settings on the desktop seem to be pretty much on or off but not by iOS device?
now, having said that, I see another post from you that seems to indicate I may be able to accomplish this by selectively using the "Enable Offline Editing" on the two devices... is that true?
Got it. This is not possible with the current verion of Lightroom Mobile. - Guido
Thanks... I was thinking that was the case but don't really have enough empty space on my phone to do a proper test - the first time I installed LR on the phone, the sync stopped because it filled the phone completely.
I'll wait for a more sophisticated version before reinstalling on my iPhone (or for a 128gb iPhone :-)
