The location tags can be used in any category, so I’m not sure why you ran into that error. I went ahead and added the tag for you on the thread, for now. I’ll see if I can look into it more later.
Okay, I got distracted and looked into it more right away.
Apparently, I had the tag set up with the “Tags are visible to everyone, but only the following groups can use them” setting with no groups selected, which meant only admins could add the tag. I don’t know why it was set to that in the first place, so I changed it to “Tags can be used by everyone”. It should work now, please confirm.
Yep! Looks like they all show up in autocomplete and are selectable now! Thanks
