What I find a little bit perplexing about this is that now Firaxis is scrambling to address the UI issues, but they've had streamers complaining about these same issues for six months. Did they not pay any attention at all to the people they had testing the game?
Tech and civic tree icons are at the top left (they are icons for the current tech or civic, which is confusing). Clicking on the yields on the top bar brings up a global settlement yield report. That appears to be the only report in the game.
No unit list, no trade route list, no list of religions. There is a list of independent powers hidden in the diplomacy screen (click on your own leader icon at the top right, click on the heart tab)
