New update!
Seems to have fixed a few things, although they've sent Cease and Desists to pretty much every site that's pokemon go related like PokeAdvisor, which you could use to calculate your mon's Individual Values (IVs) and was basically just a companion thing that didn't alter the game in any way at all.
On the bright side, they put the battery saver back onto the iOS version, the tracker has been improved (although still far far far from perfect), and you can now change your username once if you so choose. It also now warns you when you start to travel above a certain speed and prompts you to confirm you're not driving the vehicle you're in. Not that that matters to me, when I take the bus during peak hour, I go so slow that it doesn't even get to that point and all of my eggs hatch. It's great (Y)
On also brighter news, I've managed to keep my vaporeon in a gym for two days straight now, that's like a lifetime in this games' terms. So close to being able to buy more egg incubators without spending any real world money. aww yiss
