i have had the same issue, naturally I suspect an update.
looks like handwriting recognition is limited to english us after all the updates filter through.
In the language settings i added english us as second language, the used english US when writting and english UK when typing.
settings , time and language, language
or when you change the keyboard there will be a short cut to the language settings.
Once there is More than one language in the preferences you can toggle between languages in the keyboard options.
cant help those writing in a language other than english, sorry.
