Hi,

we have recently upgraded from the 2024.06 a12 version to the 2025.06 a12 version. Our Date and Year pickers were previously displaying the month in german. Now they are displaying it in english. How do i change that back to german again? Are there any settings missing?

Many thanks in advance!

Reading the migration instructions helps. Adding

<DateTimeContext.Provider value={{ locale: de }}>

worked.
