You can definitely withdraw your ID in iNat Next. Tap on the three dots on your ID and you’ll see that option. I’ve done it multiple times. If it doesn’t work then there’s a bug in the app.
As we’ve said, not all functionality is ready yet. Functionality for Projects will be coming.
This is true, but there have been some experiments done where the model can show you what part of the photo it’s relying on. We tried it out a bit and it was pretty cool seeing it highlight part of a Vanessa butterfly’s wing, for example. Making the model less of an impenetrable “black box” is something that would be great to do. But it would require a good amount of design work and I don’t know how feasible it is at scale.
