收到了approval notice但状态还是received

今天是case was received的第97天，还是没制卡。

下午拿信件的时候发现了USCIS寄来的I797，说case approved了。回去上网一查，不管是egov.uscis.gov还是my.uscis.gov，状态还都是case was received，不知道是什么情况

今天收到了卡，报一个175号段的dp:
2/26 寄出材料
2/27 case was received
6/3 邮箱收到i797 approval notice，此时egov和myacoount上的状态仍然是case was received

6/4 下午egov状态变成picked up by USPS
6/5 收到卡，而此时myaccount的状态仍然是received...
总共历时99天。最近制卡很慢，祝各位都能百日内拿到卡
