My sister is trying to send me her lightroom catalog with smart previews to edit for her. We have had no problems doing this on my computer but i recently picked up a new ipad pro and would like to start using that to cull/edit. When i open the dropbox folder with her lightroom catalog in it, it is grayed our and wont let me open it on the ipad. but works fine on my desktop. is there a way to get the catalogs/smart previews to work on the ipad pro without loading them into my desktop Lr then syncing it to the ipad. This is way to time consuming.
