Note that it's still possible to click through the vault rewards, it's just inexplicably harder to do. You just need to immediately and quickly click/tap when opening the tokens, and it will [usually] skip through the animation.
I can't even fathom the logic behind deliberately trying to slow down this process.
I love the "targeted reward" option, but it's probably a tough sell because if a user makes a mistake, that's potentially a lot of unintended open tacos. Granted, the right UI and prompting could probably take care of that part.
