皇冠体育会员反映投注不了

皇冠体育会员反映投注不了，显示 "系统最佳化中请稍候"，请问这是什么问题呢？

由于系统正在升级所以目前无法进行投注，请稍后再查看。

Members of Crown Sports have reported that they are unable to place bets and are displaying "System optimization in progress, please wait". May I ask what the problem is?

Due to the system being upgraded, we are currently unable to place bets. Please check again later.
