God.
This new UI.

I pick a class.
Goodbye, you're in the menu. You can't customize anything now or be able to click anything in the menu, as an error will appear saying you can't join anything as you're in the progress of a match.

I swear to God Ubi has done this in order to waste our time. You will have to restart the game and find another match, wasting 10 to 12 minutes or so and essentially "re-rolling" what would have been a victorious match for you.

This is the most scummy thing in the universe, Ubi. Your developers could fix this in 10 minutes, but you won't message them. You message community managers instead who go on vacations and do nothing -- Not a single post of acknowledgement from them in the centuries this game has been "developed" for, for ages. You will, of course, message one person who will just sensibly chuckle at the problems us "plebs" are having to deal with by attempting to play an amazing game in dire need of character reworks and reverting the incredibly unfair changes to the gameplay...

This might have something to do with trying to activate the boost. I press 3 or click on the button "3" and I bug out, not being able to go back to the normal screen of loading the game in the lobby. Sometimes I manage to succeed and "go back to the normal screen", to un-bug the menu messages being stuck and only being able to move between them and have the error appear.
