请问这种情况卡是不是寄丢了？要申请新卡还是再等等？

SSN上个月已经收到了，EAD到现在还没收到。USCIS网站上说5月2号收不到就申请新卡，现在已经过了三天了。请问现在该怎么办？如果申请了新卡，之前的假如又寄到了是不是也会作废？
USCIS网站显示的状态如下：
Card Was Mailed To Me
On April 17, 2019, we mailed your new card for your Form I-765, Application for Employment Authorization, Receipt Number YSC1990141XXX, to the address you gave us. If you do not receive your card by May 2, 2019, please go to www.uscis.gov/e-request to request that we send your new card to you. If you move, go to www.uscis.gov/addresschange to give us your new mailing address.

USPS那个informed delivery我申请不了，地址invalid

USCIS网站说应该会给我一个tracking number（“If Case Status Online indicates that the card was mailed, you should be provided with a United States Postal Service tracking number”），这个我也找不到。

我查到了卡确实是没寄到，被退回USCIS了。我在USCIS网站申请了重寄，但是根据网上说的，USCIS重寄卡“nototiously slow”，我现在非常担心90天的问题，有人了解相关情况的能给点建议吗？
