That's very concerning, because I upgrade from 15.1 to 15.2 without going through the registration or password login step again. (I use fingerprint unlock).Yes you are correct.
You can try this workaround: downgrading Singpass to 15.1 first, login to 15.1, then upgrade to 15.2, then block services/providers, and see if you can pass.
But if there's really issue with the login when the services/providers are disabled, then this method of blocking services/providers is not suitable for the long run also.
shiok!Bought the Pixel 7P.
but you can only activate Singpass/banking apps on one phone at any time, so maybe you don't need to visit this thread anymore.
