Ah, well, my device also has more RAM! (4GB which is still not a lot- theirs probably has the 3GB)
Everything else looks great, so why can't the shadowing effects be imported! It's a shame since the internal shadows look great then our external ones have been ruined.
The 3rd gen iPad Pro 11 inch (what I have) can have either 8GB or 16GB RAM, mine has 8GB, so I'm not sure where you're getting 4GB from
