Rivian Owners that are leasing your vehicle(in Michigan)!!

Fellow Rivian Owners in Michigan, I’m looking for your guidance on something that my guide just shared with me.

For context, I’m trading in my vehicle that is currently financed through GM Financial. Rivian approved my trade in, confirmed the lease details of my Rivian, and shared the contract for me to sign. I signed the contracts and finished all purchase tasks so I thought I was good until I received the following message from my Rivian guide: “The purchasing team, who approves all the documentation, has informed me we won't be able to transfer your plates because MI won't transfer plates on leased vehicles. Instead, we'll plan on registering you new plates!”

Is this normal? I did some research and confirmed that Michigan SOS allows for plate transfers. Is this a big deal? Should I expect additional fees because of this? Is this something I’m in the right to push back on?

Any advice would be appreciated, thanks in advance for your help!
