企业微信API生成的联系我二维码, 使用个微扫描后出现如下情况 [图片] 首次识别提示二维码已经失效, 无法找到对应的微信号, 第二次识别可以正常识别

配置两个联系我,两个联系我配置的是同一个企微成员 流程 同一个微信用户扫a的联系我二维码码返回 {"changeType":"add_external_contact","createTime":1638351194,"event":"change_external_contact","externalUserId":"wmM6MpDwAAaToLvgIV_2nYF4y-Aeu-Ow","fromUserName":"sys","msgType":"event","state":"FCC2021112920343301797d7","toUserName":"ww818ee4cb4ce65899","userId":"tongcheng8914","welcomeCode":"wSAKPX4uvLGIliQXIOahPz9eTdIphx0kQXRzfBTPBPQ"} 后删除企微成员好友,继续扫B的联系我二维码 {"changeType":"add_external_contact","createTime":1638351266,"event":"change_external_contact","externalUserId":"wmM6MpDwAAaToLvgIV_2nYF4y-Aeu-Ow","fromUserName":"sys","msgType":"event","state":"FCC2021112920343301797d7","toUserName":"ww818ee4cb4ce65899","userId":"tongcheng8914","welcomeCode":"XXSYAaAFZ3yeU1jChmu7fHe4y4H0hjjYb7QzEJYarFE"} 两次返回的是同一个state

请问服务成员（企微成员）删除了客户，再次添加回该客户，还会给该客户发送欢迎语吗？
