Jeff Graebner@drsbaitso I wish I had come across this summary before I basically went through the same process earlier this weekend. I did discover a couple things that weren't noted in your summary. (1 of 3)
@drsbaitso 1. If your Adobe account has 2-factor authentication via an authenticator app, Editions won't prompt for the code. Instead you have to use "<password>:<code>". Without the code, it just gives an "Invalid username or password" response and I had to search out a well-hidden support document to figure out how to make it work. (2 of 3)
@drsbaitso 2. One brand of eReader device that doesn't work with Adobe DRM is Amazon Kindle. I guess Humble didn't think that was worth mentioning since it only has a 70% market share. (3 of 3)
