I checked in instant.page again and now it works. I closed browser a couple of times if it was something needed to be cached, but still worked so no errors. I don’t feel safe to have it activated though until you make sure disabled checkout also disables instant.page on checkout 🙂
Solved. Please feel free to remove thread:
