Hello, I would like to ask why the electronic signature of word is invalid when it is changed to transparent WeChat. Changing the electronic signature of Word to transparent WeChat failed because the setting was unsuccessful. When the word electronic signature is set to transparent, it needs to be saved again to avoid the failure of the transparent electronic signature that was not set successfully on WeChat because it was not saved and opened after exiting. Therefore, it is invalid to change the word electronic signature into transparent WeChat, because it has not been set successfully.
