Keno,
You’re right on, it was a MutableLiveData object previously and I changed it but missed the snippet here.
And you’re not annoying at all, I’m legitimately excited to see that you’re working through it and that you’re sending along this great feedback. I want to make sure the book’s as good as possible and you taking the time to help ensure that is wonderful.
Fixes/updates for all three of your posts will be included in the next beta release. Thank you again!
