Got 2 Model Y's 2023 - Question about FSD

Hi Everyone, Was fortunate enough to buy 2 Y Tesla's today, both 2023's. 1 is the Performance (HW4) and one is the Long Range (HW3) My question is the Performance when I go to upgrades it shows me the FSD subscription and the connectivity option. On the Long Range one when I go to the bottom of the screen under Upgrades, it shows Upgrades Unavailable - No Upgrades are available to purchase from the vehicle at this time. Check on your Tesla app. (Retry) Has any encountered this? My phone app is not yet setup since I just uploaded the documents, waiting for the old owner to approve the transfer. So currently using the Key Card for now. Hoping he/she gets the email and transfers/approves it. Anyway do you think its part of that? Once its transferred I will be able to see the upgrades or is it a hardware issue? I do have the HW3 on that, isn't it compatible with the FSD? So new to all of this and learning as I go. Thank you everyone.
