"Hello,
We'd like to apologize for the slow pace of updates following the launch of Tennis World Tour.
Game development is a complex process and despite our continuous hard work, there have been a few roadblocks that stalled our planned patch schedule.
We're committed to providing a fantastic Tennis experience for fans of the sport and for everyone who purchased the game. Over the past few weeks, we've been working non-stop to iron out these issues and will have more information to share in the near future.
We are sorry for the wait but would like to thank you for your patience and understanding as we further build upon the TwT experience."
