Congrats! I sow that locks for Europen jls, I think it is amazing! I hope mine had oneI've had my 2020 Sting-Gray JKUR for about a week now. Coming from a 17 JKUS.
I also noticed the steering was very loose initially, but has been better since I adjusted the tire psi. Same with the transmission "flutter" upon slowing down. Otherwise, I think everything is very much what I saw in the 2019s so there is nothing dramatic I've noticed so far.
One minor difference I did see is that my 2020 JKUR came with a hood lock keyed to the fob. This wasn't on my invoice so I assume it is standard now?
