I had powered off my echo vor 3 months and when i reactivated it, i had to reset it completely as it denied to see my wlan. After some struggling, it now works again including harmony as well as homematic device control. But when i went into config to switch from „alexa“ to a different activation word, the config shows „activation word loading ...“ and stays at it. As alexa accepts all commands, wlan connectivity can not be the problem. I retried several times over the last 2 days... what blocks that choice?
