Finally! My app is reporting no problems!!

I've had a 2024 P2 LRDM with Plus & Pilot packs since January. Since then, the app on my Android phone has displayed a "12v battery low" error. I brought the car in to the service center twice to try to fix it (they said my 12v battery tested fine), and went through lots of troubleshooting steps such as resetting TCAM and going on long drives, and nothing helped. After some back and forth with their support, here's what finally fixed it:

1. Update software to 5.0.10 (or later, I assume)
2. Unpair car from in the Polestar app on my phone
3. Clear app cache for the Polestar app on my phone
4. Clear app data for the Polestar app on my phone
5. Uninstall Polestar app on my phone
6. Go to Bluetooth settings on my phone & remove/forget anything related to Polestar
7. Delete/unpair phone from in the car
8. In the car, go to Settings, reset options, factory reset
9. Wait for reset procedure to finish. Wait for TCAM to reboot (SOS light on the roof will stop flashing and turn white).
10. Go through initial setup
11. Reinstall app & re-pair app with car
12. Wait 20 minutes

Just in case anyone else has this problem, this is worth trying.
