Extension:
1. Technical limitation: Some functions may be limited by software or hardware, which makes it impossible to modify the link name. This may need to be solved by software update or equipment upgrade.
2. security considerations: some applications may restrict users from modifying link names to ensure the security of user identity and privacy. This can prevent malicious users from abusing or misleading other users.
3. design choice: sometimes, the design choice of the application may not include the function of modifying the link name. This may be because developers think that this function is not a priority, or they think that fixed link names are more convenient for communication and identification between users.
in the face of the inability to modify the link name, users can try other methods to distinguish different links, such as adding key information in comments or descriptions, or sharing other identification marks with participants, such as personal head portraits or specific identifiers. At the same time, users can pay attention to software updates to obtain a new version that may contain the link name modification function.
