My skill has an intent with the following utterance "ask smart dry find my sensor" -- smart dry is the skill invocation, there are no slots.
When I say this sometimes the correct intent is triggered (10% of the time) but usually I get "Smart Dry did not understand" i.e. the fallback intent was triggered
When I go to the activity screen in the Alexa app, the voice feedback says
Alexa heard:"ask smart dry find my sensor".
If I type the same thing in the development console test page it works every time.
Why wasn't the correct intent triggered when alexa heard the correct utterance?
