2 accounts consistently reporting the same IP, location and user habits etc being linked is more absurd than nobody ever noticing excessive uploaded data from their phones? It is very easy to monitor the amount of uploaded and downloaded data on a device, lots of people would have noticed by now. The amount of storage, bandwidth and processing power that would be required to monitor the audio from hundreds of millions of android users globally 24/7 would make this the dumbest business decision ever when there are so many easier and efficient ways to track users.
Lol I spent a week going back and forth with Revolut support in august. I could sign into the app but it would always ask me for a “selfie” verification and every time support would say its a super dark selfie.
Eventually I decided to try a stock ROM and it just worked and I realised what was happening so I transferred all of my money out and deleted my account.
Most local banks here are terrible at making apps, some even require a separate device that looks like a calculator to use online banking, so hopefully they wont follow suit anytime soon
