What is confirmed
The Day One announcement says Patch 1.0.1 addressed a cross-play matchmaking issue experienced during Early Access. It does not guarantee that every modern connection problem has the same cause.
Practical approach
Confirm that every player is updated, then consult current official service notices before trying unsupported fixes.
