So: when opening the potato server list on a normal web browser (https://potato.tf/servers), I'm able to click the map/server's ping button to connect to whatever map or team is currently engaged in bot-smashing.
BUT: When opening the server list on the TF2 in-game browser thingy, post-UI update, and doing the same thing, I'm not redirected. It's a click without a response - the little icon displayed shows a change, sure, but I'm not loaded into a server. I can, of course, just open the menu outside of TF2 to connect, but it's a bit inconvenient.

Anyone else experiencing this, or finding a workaround?
