I'm not sure about the newsletter but from what I know, the EOL was for Crestron Mobile Pro apps, which are pretty old. The Crestron App for Android was the replacement SG version of the app since 2014. It's confusing because the Crestron App (for Android) and Crestron Go are really the same thing.? Both Android and iOS versions were once just called "Crestron App for Android/iOS" but there was a SNAFU with the iOS version where they had to change the name when it was removed from the app store from Crestron App to Crestron Go. Maybe the android version should be called Crestron Go as well to remove any confusion. Here's a link for you.?
