I agree that we do need some solutions. Like you, I don't have any issues with anything else in my house (PS4, Switch, phone, laptop), nor do I have the issue with any other online games I play.

I will say that since starting to use Mudfish a couple of days ago, the problem seems to have more or less gone away. Whether I'm just lucky at the moment, I'm not sure. However, it's ridiculous that I need another program to make the game playable.
