Tagging Photos Across Logins

I have photos in shared folders that I'm having problems tagging (or seeing tags) across different OneDrive accounts using the desktop app. I can add & see tags in some, but not others and vice versa. Some photos won't allow me to add tags at all. I have checked to make sure the files accept tags, tried multiple computers loggged into the same OneDrive account as well as those I've shared the file with and can't seem to find how/when I'm given the "permission" to add tags or not. Also odd that sometimes the tags show up across devices/accounts while others don't. Please help!
