I've just installed Lightroom Mobile on my Mac and my iPhone.
I read the Lightroom mobile tip under the Help menu that explains that I should click on the boxes beside a collection to get it to sync to Lightroom mobile:
And I've watched the Lightroom Mobile - Setup, Collections and Flags video that describes the same process:
But in Lightroom on my Mac those checkboxes don't appear.
I can confirm that I am logged in to my Adobe ID, which I understand is required. I am subscribed to the Adobe package that include Photoshop and Lightroom.
So I'm a bit confused. It seems like it's a simple matter. Is there some additional trick that I need perform to get those checkboxes showing up so I can sync with Lightroom Mobile?
It's weird. I have logged in using the Lightroom app on both my iPhone and my iPad and I can sync photos between those two devices. But not in Lightroom on my Mac.
I tried logging out of Lightroom/Creative Cloud on my Mac and then logged back it, but that didn't change anything.
Hm. Figured it out.
Under the nameplate, "Sync with Lightroom mobile" was turned on. I toggled it off, then back on again, and the boxes magically appeared.
Frustrating, to say the least, but it worked.
