I created an optional tag for the AnKing Overhaul deck shortly after the feature was released. The tag is called “!NSU-KPCOM”. I tried to create this same optional tag for a different deck on AnkiHub, but I am now getting an error saying that I can only use letters and underscores. The new tag would have to read “NSU_KPCOM”. I’d like for both tags to be the same for the sake of consistency.
I don’t mind the new tag name, but how can I safely update the tag on my end to ensure that all subscribers also receive the change?
