Issues with new Amibiclimate component

Hi you all,

I have issues with installing the new Ambiclimate component.
I followed the instructions. After creating application on Ambi API site and adding client_id and client_secret to the configuration.yaml, I restarted Home Assistant and added Ambi on the Configuration page. There it asks me to authorize the API via https://api.ambiclimate.com/oauth2/authorize?client_id=

But when I click “Accept” nothing happens. It does download an STL file with “OK!” in it, but that’s it. No confirmation or anything. When I go back to the Home Assistant Config Screen and click “Submit”, I get the message " Aborted. The Ambiclimate account is configured." which in itself doesn’t make sense. After that, I get the temp and humidity readings, but I cannot control any of the AC’s and I get error messages such as 'Failed to call service climate/turn_off. ‘target_temperature’.

Any help is tremendously appreciated!

Cheers, Marc
