I did set my settings to 24hours on the device. While being in the “date & time” settings screen it displays the time in 24h mode, however still on the top of the screen it is in 12h mode. When leaving the screen and returning to the home screen it also shows the time in 12h mode. Once the screensaver starts again in 12h mode.
Thanks @Agostino - we’re on it. Will roll out a fix in the next week
