Does this function similar to a “Private Space” on newer Android or “Secure Folder” on Samsung?
No. Unlike those, you dont have to unlock the app nd use them, the sandbox is just a normal apk but it dosent allow gservices root access and blocks most telemetry, leaving only the necessary APIs
If you want a total user sandbox, you create another user and install gservices there.
Are there problems with OTP in this environment?
There are like 30 ways to send/generate an OTP.
At least where I live there are laws to collect this info. Is it not regulated in Murica?
This just dosent make ANY sense. Sim swaps are done via social engeneering.
If they wanted to be private, it would be Open source.
Since when do people send 2fa codes via voicemail? The fuck? Just use signal.

Also, they DO collect your Credit card data. Not they themselves, but Stripe. So Stripe knows every detail about you.
