Civ VI + Steam controller bugs

tl;dr: it's 99% playable, but a bit clumsy and sometimes you need to resort to the mouse for UI bugs.

I tried playing Civ VI with the Steam controller right out of the box with no custom configuration (I borrowed the controller from a friend, never used one before). It feels alright for most gameplay, but there are some teething issues I'd like to see fixed.

• Dismissing notifications ("city state wants gold" etc) from the right hand side, the "right click" with the trigger "falls through" the UI and causes a click on the map, which will make unwanted moves. Super annoying, must be fixed.
• Drag & drop of the "cards" in the government screen is really super clumsy, needs two hands: press A button with left, use touchpad with right. Would be better without drag & drop, just a (double?) click.
• The B button closes some dialogs but not all. e.g. Tech tree closes nicely but some modal dialogs need to be closed with the pointer.
• Left touchpad doesn't do anything, zoom/scroll is mapped to left/right shoulder buttons. Feels clumsy with discrete steps, not smooth.

Is there a place to file bugs for Civ VI?

Please share your experiences with the controller, and/or link to any forum threads about it. I'm sure there are tons of issues that I have not come across yet.

I find appaling that there were controller bundles advertised together with Civ VI, but then it doesn't work butter smooth out of the box. I'd think this kind of promotion deals should include throwing some QA to make sure it works like a charm. If I would have bought the controller for this only, I would be mildly upset.
