I'm on PS4 and have experienced this issue daily for the past four days in WoC 6's Drop-In.
If I somehow get into a match, the game often freezes before puck drop, or disconnects (either me or my teammates) at random.
Whenever I can't get into a game (after waiting on the "Searching" screen for 10-20 minutes), I close and restart the game. I have to close the game because, if I press circle to cancel my matchmaking search, I am left on a "Cancelling Search" screen that never changes (or, for some reason, canceling may put me into a group of other users whose searches have also failed).
After restarting my game to retry WoC matchmaking, I am unable to find any matches in 6's Drop-In and sit on the "Searching" screen for an indefinite period of time, doomed to relive the same garbage fate that you have foisted upon the NHL community.
Please, fix the game. I paid for the game because I want to play World of Chel. I have a great, wired internet connection and can count on one hand the number of issues I've had with other games in the 5 years that I have played online games with my PS4. I thought connection problems and game-breaking errors were bad in NHL 22, but trying to play WoC in NHL 23 is, by far, the worst online experience I've had with any game that I ever played.
