Your questions are all good. I assumed that you were doing edits directly on the preview image before licensing it, but it sounds like you aren't. If you are doing edits on layers, that is good. I just realized that I missed an important step in my directions. The preview image in the layered PSD edit file has to be linked to your CC library where the actual preview image lives. If you double click on the preview to open it, make edits on layers and save that new file to your computer, there is no connection back to the file in the library. Here's how you can fix that: Open the edited PSD file that has the edit layers. Drag the preview (or licensed image) from the CC Library into the document. You will see a link icon in the layer panel showing that it is linked to the original in the Library. This should fix your problem.
