Stuck Downloading update

So, at 7:35 UK time this morning, my car said 2021.40.6 was available and it would take 25 mins. I started it as I didn't need the M3P still 8:40.

At 8:40 the screen on the phone app showed "Software update... Downloading 2021.40.6 (100%)"

And the car is similar, as in the software screen shows 100% and it sits there.

I panicked the car wouldn't work, but it did and it shows (on the app) 2021.40.6, but is stuck downloading at 100%.

So it seems to have done the update but is now on some limbo state. I rebooted using buttons only, then buttons and brake, no difference.

Ideas ?

As long as the car reports the current version as 2021.40.6, I wouldn’t worry about it. You can try a power off reset to see if that helps. From the manual:

Power Cycling the Vehicle

If your vehicle demonstrates unusual behavior or a nondescript alert is present, you can try power cycling the vehicle to potentially resolve the issue.

1. Shift into Park.
2. On the touchscreen, touch Controls > Safety & Security > Power Off.
3. Wait for at least two minutes without interacting with the vehicle. Do not open the doors, touch the brake pedal, touch the touchscreen, etc.
4. After two minutes have passed, press the brake pedal or open the door to wake the vehicle.

Note that pressing the brake during a scroll wheel reboot doesn’t make a difference. It might have at some point in the past.

My Tesla mobile app shows it downloading software update 2021.44.25.2 for my Model X but it has been stuck at 44% for days. The car's screen however shows v44.6 as downloaded and up to date as of today. I have deleted and reinstalled the mobile app but it still displays the download stuck at 44%. Any ideas on how to get rid of this download notification?
