Having changed the Alexa invocation name in developer portal and building the model didn't work with Echo device. It keep responding to old invocation name and keeps saying 'I am not sure about that' for the new.
Old invocation name: my genie
New invocation name: deakin genie
To further complicate the matters, the Alexa test simulator in developer portal and the Alexa mobile app work perfectly with new invocation name and doesn't respond to the old any more which is the right behaviour.
The preferred invocation word is the new one but change hasn't been effective after 2 hours since the change. What can cause this?
