Reported. Map hue currently not working.
b. Please double-check the API key that you've added, and make sure you've activated it.
Reported. In the meantime, please check temporary solution on this thread

5) Video pop out
We won't be able to have total control over the Opera browser as they have built in codes with that. Our fixes are limited only to the DOM which is on our websites.
A lot of users however have requested this video pop to be disabled by default. I have already submitted the same feature request to Opera. I'll let you know once I got a reply.
Hope these helps. Let us know how it goes.
