Subscribed to FSD but not activated

[T3SLA90D]

My 2016 MS has MCU2 and HW3 and had working FSD until I transferred it to the new car. Now a month later I wanted to subscribe to FSD on the old car for a month for a road trip. I purchased the monthly subscription yesterday at noon but it’s not yet available on the car. My car’s firmware is 2024.20.1.

Does the firmware have anything to do with FSD not activated? Thanks

that is a very old software, unless its a typo...

Sorry it was a typo. 2024.20.1

Did you try rebooting? There’s no reason why FSD shouldn’t be available immediately if you subscribe.

I did. I’m wondering if some advanced firmware branches are not compatible with FSD?

I just got it. Took a day and a half. Thank you.
