Lightroom mobile requires Internet connection to sync Pictures from your Desktop Computer through Cloud
So you need Internet connection to sync your Pictures
thx is there is a place where we can suggest this feature ?
for example i can generate smart prev then send them to my ipad through lightroom without internet
and when ever there is connection it will update the cloud ?
Lightroom mobile only sync smart Preview of your Pictures
So Once you have sync pictures(Collections) in Lightroom on your Desktop
The next time you open Lightroom on your Mobile devices with an internet Connection
You will see your Collections start syncing
You can request for a feature here
Hope this helps
