Why can't I see the credit report sent to qq mailbox?

The reason is that the email was mistaken for spam and the email download failed.

1. mail is mistaken for spam: the spam filter of QQ mailbox may identify some strange mail as spam and automatically move it to the spam box. You can check the spam box in QQ mailbox to see if there is any mail you need.

2. Email download failed: sometimes the attachment in QQ mailbox may fail to download due to network reasons or other problems, resulting in failure to view it normally. You can try downloading the attachment again and view it.
