This is one of my big gripes - when apps are trying to get ahead of me with validation or submission. When I'm entering a 2fa code, I don't need a big red error telling me that the code must be 5 digits before I'm even finished. Worse is when they immediately auto-submit upon entering the last digit, so if I made a mistake I can't backspace and correct it
