The old 'Adobe Photoshop Lightroom CC2015' is what is now called Lightroom Classic. Lightroom (version 3.0) is a new and different application, that stores the originals in the coud. If you mainly want to work independently from the internet, then you did indeed get the wrong plan. Contact Adobe to change it to the Photography Plan with Lightroom Classic.
Thank you! I will be reaching out to get my plan switched over. Odd thing is that it looks like the same money buys Photoshop as well as Lightroom and Lightroom Classic. 20GB of cloud vs. 1TB (which really doesn't matter to me),, I wish I had looked deeper into this prior to pulling the trigger on Adobe Photoshop Lightroom..
