Answer 1

When you make your .find() call, your collection isn't done updating yet.

You can choose to call .find() in the callback of your .update() call, or you could also use promises or async/await depending on your version.

Another solution would be to use findAndModify with the new option:

Optional. When true, returns the modified document rather than the original. The findAndModify() method ignores the new option for remove operations. The default is false.
