We recently had a tow hitch installed at the service center and I also asked to have them install a roof rack we had ordered for our 2020 Model Y. They did not install the roof rack and scheduled a follow up appointment, with this text in the invoice "Technician was unable to install roof rack due to fitment of the roof glass. Roof glass is on order for replacement at a future visit". I have not seen this, and am not sure what it means - should we go ahead with the installation? Have other people gotten their roof glass replaced when installing a roof rack?
