点击合作者确认链接的时候，有时候会出现：This action is not currently available. A login session for a different user ID is still active.

一般如果你有一个已经打开的会话，或者如果链接已经被点击过，通常会显示这个错误。解决方法是在再次点击该链接之前，请关闭任何打开的会话，并清除浏览器缓存。

或者，你可以复制该链接并将其粘贴到你不经常使用的浏览器中，并尝试以这种方式登录。

比如，在我们换了浏览器之后，可能会出现：

This journal encourages authors to link to their ORCID record to retrieve an 'Authenticated' ORCID iD. This will support the correct attribution of this manuscript to you if it is accepted for publication. If you have not yet registered for an ORCID iD, you can also use the Link to ORCID Record button to register and authenticate a new one.

这是因为没有绑定orcid，可以不绑，直接点击submit即可，之后便会出现确认成功的提示。

当然，如果出现：

This action is not currently available. You may have already affirmed or declined your co-authorship status, or you may have been removed from the submission.

Please contact the publication for additional details.

就表示之前已经确认过了，可以放心了。
