I’m unsure if this is just a problem on my end, but is there a way to add or edit an existing key to a user that currently does not have the meta data set?
For instance, I have a key/value pair set for a single user through update_user_meta() by a plugin. However, I want to set the same key for another user with a different value. But if I click “Edit Meta,” the key does not appear in the drop-down menu. If I attempt “Add Meta,” it will state that the key already exists.
Would this be a possible feature? Or is there an alternative?
