The AA Coolwalk interface appeared on my 2020 RX this morning. AA updated to 8.7.6xxx yesterday, which may or may not have triggered the new UI. I like the new interface so far. It handles notifications better and allows the full screen map. I was concerned that the menu bar might move to the bottom the screen; not a good idea with the very wide aspect ratio of the RX 12.3" screen. Thankfully, the menu remains vertical and on the left side.
