I have a skill for controlling my Squeezebox media players. It uses PowerController, Speaker and PlaybackController interfaces from the Smart Home API. When I add a ToggleController interface the endpoint becomes unresponsive. If I delete it and re-discover without ToggleController, it always gets re-discovered. With ToggleController included, it is not discovered. It does show up in my list of endpoints if I examine the JSON manually but Alexa does not report it.
I am a customer of Amazon.co.uk with a skill for the en_US language and ARNs both in Ireland and in US-East Viriginia. When I originally created the skill, it was Ireland only and I added Virginia recently. Cloudwatch logs show activity in Ireland but none for Virginia.
