Your API, which is also used by Alexa, is terrible slow!
I just bought two bots and a Hub Mini. I would like to use them with Alexa or directly with your API. In both cases it took over 5s until the bot get the command from your API service. This is too slow so that the bots can't be used.
Please upgrade your infrastructure otherwiese no one can use your bots with Alexa or with the API.
I live in Europe, I don't know whether you have different API servers for each region, so it could be only an performance issue in Europe.
Of course it is not an issue of my local WiFi or internet connection. It is definetly an issue of your server infrastructure.
