What should I do if the WeChat bill is sent to the mailbox after it expires? You can click Update.

If you still can't open the file after the update, click Enter My Transfer when you receive the file, so you can directly save it in the mailbox and download it directly. If you still haven't received it, you need to resend the following.

The documents sent to the mailbox should be accepted in time, or the acceptance time should be set to avoid the expiration of the documents.
