I'm not able to import photos. I've connected the card reader, but the top left of the screen says "Get started with lightroom mobile, instead of telling me where the photos are coming from, as has always happened in the past. The middle of the top has nothing at all, instead of "copy". Please help.
Sounds to me like you are not in the Import dialog box.
What happens if you select File->Import ... ?
If that's not it, show us a screen capture.
