Germania
I am in U.S using the Windows version of SF. I tried a third time with same result - audio is AAC and drops out. I was going to post images of the download dialog with EAC3 selected, and of MediaInfo showing AAC. But for some reason when I click the “Add an Image” icon at the bottom of the reply screen, it instead inserts the same thing that it does if I click on the “Add a link” icon which is this: 
Maybe I just don’t know how to add an image.
I updated to the new version from within the app. Might it make a difference if I uninstall SF and reinstall it?
