Is an ASK authored Alexa skill compatible with all Alexa devices past and present?
I'm not talking about the desirability of enabling a visual if the device has a screen. I want to know if there are exceptions to skill capabilities on Alexa devices
For example, if I was making a web app, there would be browsers I would not support where they lacked a key capability as they were outdated and could be ignored as their market share is insignificant (for some definition of 'insignificant')
How would I know if core functionality, for example Audio Player, is unsupported or unreliable on, say, legacy devices? Does a list/ table exist?
