Actually, I just did a major upgrade. Please read here: [RELEASE] Alexa Helper
In summary, there are two versions now…Version 2.2.2 which is a stand alone app that will no longer be supported (Now called Alexa Helper-Original).
The new version has two parts (a parent and child app). This is version 3.0.0 and available in the link above. It sounds like you installed the Parent app and are missing the child app. Please note…on the child app do NOT publish it…just save it.
