Has anybody else tried the new "Alexa says" action which has been added to Routines?
It allows you to select from a range of categorised phrases for Alexa to speak when triggering the routine. Unfortunately you are limited to that selection of phrases, you cannot create custom phrases. Also, behind the scenes, it appears to use the "Simon Says" functionality.
This means it is subject to the same issue as "Simon Says" (may only be an issue in the UK) where Alexa will randomly say "I heard phrase" rather than just repeating the phrase.
I tested a routine which starts of by saying "Good morning", triggering it several times, and it randomly says "I heard good morning" instead which spoils the effect somewhat.
