I notice this text appears to be a mix of Russian and English content about YouTube, with some fragments about legal/tax services in Moscow and news from TASS. However, the text contains some issues and doesn’t form a coherent question.

Let me address what I can understand:

YouTube app descriptions ― Repeated marketing text about getting the YouTube app on iPhones, iPads, and Android devices, mentioning features like music videos, gaming, fashion, beauty, news, learning, etc.

Russian legal/tax references ― Mentions of «Межрайонная инспекция Федеральной налоговой службы № 46 по г. Москве» (Interdistrict Inspectorate of the Federal Tax Service No. 46 for Moscow) dated December 30, 2015, and a Moscow law firm «БЕРЛИН» (BERLIN) with news from April 22.

A YouTube challenge/event ― Something about «Chewkz and SaeedTV_» in a «Mystery Box Challenge»

Extended reality/VR mention ― «Experience your favourite YouTube channels… in extended reality»

— The opening «Тема: Today is…» seems garbled/incomplete`) scattered throughout
— The text jumps between unrelated topics without clear connection
— Some Russian text is cut off or malformed

Are you looking for:
— Translation of the Russian parts?
— Explanation of what this text is about?
— Help cleaning up this text?
— Information about YouTube apps or services?

Please let me know how I can assist you with this content.
