I have an Alexa skill, which was developed around a year ago. I haven't touched it for a while, now I would like to use it. I thought there will be some problems because of API changes, but it seems to be working fine. In the emulator.
I have some responses, which I send as progressive response, these are showed in the emulator as "audio only response", but when I try it on a device, or the mobile app, these response are not read by Alexa.
Does anyone have an idea what can cause it?
