Does the subject want to ask "What is the reason for the inconsistency of the signatures displayed in the sharing activities of the express channel service"? Inconsistent signatures, sharing link expired.

1. Inconsistent signature: When sharing activities, you need to ensure that the signature of the sharing link is consistent with the identity of the users participating in the activities. If the signatures are inconsistent, you will not be able to participate in the event normally. Just re-operate the signature.

2. The shared link expires: the link of the fast channel service sharing activity is time-limited. If the sharing link expires, it will lead to the inability to participate in the activity normally, and the sharing link can be regenerated.
