Instagram has evidently made one more change, hopefully the last, to their API for publishing photos to the service. We can now confirm that users can upload to the network using third party apps like Instance, and that those photos are public (unlike the last change). That’s an improvement from yesterday, where posting was blocked only to return later, but with photos marked as ‘private’.
At this point, it is unclear if Instagram is reversing course out of good will or if this was part of their plan, with the side effect of monkeying with third-party apps. Regardless, if you have Instance on your Windows Phone, you should be able to directly post without any compromises. No telling how long that will last though.
