I didn't see any place where people had reported anything, so thought I'd start something in the location that seems most appropriate ("Technical troubles").
I noticed what I think are two errors (both minor, I'd call them typos):
"Lass uns heute im Freien Frühstücken." As "frühstücken" is a verb, I think it should be lowercase, not uppercase (contrast with the noun Frühstück, which is properly capitalized). https://en.wiktionary.org/wiki/frühstücken
"Der President hat seinen Rücktritt angeboten." I think this should be "Präsident" instead unless "President" is also used in German as a synonym for "Präsident." https://en.wiktionary.org/wiki/Präsident
