Hi, I’m encountering issues with this as well. The text styles are not showing up.
@Belinda_Kwan Hi! I moved your recent comment on the thread linked to this topic, because the one you originally replied on is an outdated one that may not be related.
Can you please confirm when was the last date and time that you saw the text styles in your library?
If you try checking the version history, are you able to restore a version of the file that has these styles? Here is how to use this feature: View a file’s version history
If you do find the version with the styles, if you restore this version, publish it again, and accept the updates in the other files the styles should be re-linked.
Also, does anyone else have edit access to the file? If so, is it possible that someone on your team cut or delete the styles at any time recently?
