Sorry to resurrect 4 months later, but ..
Mein Schatzi! Not native, but from what I recall Schatzi (usually, because it's cuter than Schatz) is not used in that passive aggressive way to a stranger like in the UK. Partners, your own children, friends, family - but people you like and love.
Will be watching the original Sissi films this Christmas, would recommend 😁 (has anyone given the Netflix series a go?) I also listen to Spotify top 10s for countries I'm learning the language of. I'm under the illusion it'll teach me slang 😂
In general with Duolingo, I've found the course quality very varied, and the entry tests inaccurate. Learning Arabic from scratch was good initially, but got repetitive and boring very quickly, not much variation, very much an unfinished course. And then they switched from the tree to the path, and the repetition got even worse 😬 Spanish is a good and varied one, but with a shit entry test (it put me too low). Swedish is too repetitive.
@veritasverity The basic free version of DuoLingo has ads, and you can't progress as quickly. I wouldn't pay straight away for DuoLingo Super. They almost always give you a few days of Super, then give you a few more days when you press 'I don't want to pay'. It's very easy to cancel. They usually do codes for 7-30 days free Super, too. Ask someone here for a referral link and you'll both get a treat.
