A recently pushed message about a routine 15 minute maintenance scheduled for 18th September 2020 is displayed at the bottom of the Launcher in a band with a red background. The message is in English, even though the user's Launcher has Polish selected for all texts. The text of such messages should be internationalised to be readable in the target language selected by the user.
Hi, this is a feature request and not a bug. Still, when we publish these messages we do them on short notice, and do not have time to make translations for all languages. Works as intended.
