As far as I can tell, none of the "health" results are about the patient's health, only carrier status relevant to potential children. I imagine that is why the FDA is quicker to approve these tests than others, because there is not much the patient can do to act on it. (In theory the test could diagnose the same diseases, but I think they are all severe enough that the patient is expected to already know. Maybe they would be diagnostic for children.)
Except that they do predict lactose intolerance. That is in the "wellness" category, which I suspect are things that the FDA said it didn't care about.
Not yet, but 23andMe is still working on getting more tests approved. It'll take some time, but at least they're making progress, and the FDA isn't totally shutting them out.

Looks like they were finally able to work out something with the FDA, and are back up and running. On the one hand, I'm very excited about the return of personalized genetic testing, but on the other hand I'm disappointed that their price doubled to $199. I was going to get kits for my 4-member family for Christmas, but that won't be feasible now.
Another interesting release from 23andme that came out at the same time is their [transparency report](https://www.23andme.com/transparency-report/), which shows how many requests from law enforcement they have gotten for customer DNA access, and what percentage they have gone through with.
