I agree, itās an oversight on our part for not thinking of a proper migration step if you were previously using punctuation tags.
There is a find & replace (itās just a bit more hidden than usual). For now you can use this as a workaround (Iām so sorry if youāve been using those tags across multiple documents, since youāll have to do this in each document)
For reference, itās been on our bug list since around 2017. Part of the reason we havenāt made the switch back then was precisely because some were punctuation in tags. It was a recent decision to change the behavior because in almost every other app, punctuation arenāt allowed.
