These issues were fixed following the update on Apr 26 (PT).
We have confirmed the following issues in Best of 3 and Best of 5 private matches:
- General connection issues
- Error Code 3102 errors
We are now looking into these issues and working to resolve them.
Until the connection issue is resolved, we advise that players and tournament organizers refrain from using Best of 3 and Best of 5 modes, especially in cases where fairness of play and competitiveness are vital factors. We recommend playing in Single Match mode instead.
We apologize for any inconvenience and thank you for your patience.
