I can't figure out how to export a Web Gallery from Lightroom CC. Maybe it's not possible? Everything I search for on this site refers to Classic. Also, I've already edited in CC and would like to switch back to Classic. Is it possible to switch and keep the edits? Again, I see info on switching from Classic to CC but not the other way around.
You export from Lr CC by selecting photos and clicking the share icon - top right. Choose save to. You can save as jpeg or original.
In Lightroom classic you can turn on sync under the identity plate provided you are signed in with the same Adobe ID. All originals in the cloud will be downloaded into Lightroom Classic and saved to your hard drive or external hard drive as chosen in LR Classic preferences.
