I'm confused about Content update frequency and I don't think I got how it works.
Let's say I set "Content update frequency" as "daily". Will that mean that Alexa will read my flash briefing feed (let's say JSON) once per day? If yes, at what time of the day? How soon will Alexa read an updated JSON feed, will that be only on the next day? Will Alexa cache the feed audio/text it grabbed from my feed until next read on the next day?
