Well, first, check if the post is from a private account. If it is, that could be the issue as private posts often can't be added to stories. Also, the platform may have specific rules about the content of the tagged post. For example, if it contains certain types of media or text that are not allowed in stories, it won't be added. Additionally, if your account has some restrictions or is in a probationary state, that could also stop you from adding a tagged post to your story.
It could be that the tags you used are not allowed or there are some specific settings preventing it. Check the platform's guidelines and make sure your post meets all the requirements.
It could be that the post doesn't meet the platform's criteria for tagging. Maybe it's the wrong format, or there are certain restrictions based on the content or your account status. Have a look at the platform's guidelines for more info.
Check the privacy settings of both your story and the tagged post. Make sure they are set in a way that allows the post to be added. If not, adjust the settings accordingly.
Well, 'tagged but can't add to story' might be related to access rights. Maybe you have tagged something, but you don't have the proper permissions to put it in a story. For instance, in a collaborative project, you tagged a document with relevant topics, but the project rules don't allow you to add it to the overall story of the project without further approval.
In a creative writing context, if you have tagged ideas that won't add to the story, re - evaluate your story's concept. Maybe you need to adjust the overall theme or plot to incorporate those ideas more smoothly. You could also consider creating a sub - plot or side - story where those tagged elements could fit better.
The inability to add a tagged story to your story could be related to the source of the tagged story. If it comes from a restricted or untrusted source, the system may block it. Additionally, your account might not have the necessary permissions. For instance, if you are on a trial version of a service, certain features like adding tagged stories might be disabled.
