I wanted to double check that Uber had properly deleted the account. I reinstalled the app, which opens on the sign up page, and clickd at the bottom "Find my account".
Suprise! (or not) Uber recalled exactly my account.
I tried to swap the sim and change the wifi, it still did the same.
The phone has no personalized ad enabled (so does not send an IDFA).
I deleted other apps from the same Team ID (Uber Eat).
The only legit way to "track" a device, as far as I know, is DeviceCheck's DCDevice. But this only stores 2 bits, certainly all the info Uber had.
It's painfully hard to escape BigTech's surveillance...
Hence my question: Is Uber illegally tracking devices, and if so anyone has ideas how?
