I too reached out via feedback. I got a mail to do a factory reset. When I pointed out that a factory reset was too drastic a step & would cause many problems, Nothing support replied they had no other solution.
Support didn’t give me an option to suggest that the OS team should work out a better solution than a factory reset.
Nothing tech should be more helpful in resolving a common problem faced by all handset model owners.
Frankly, it’s better to avoid using Private space unless Nothing comes up with an easier reset pin/pattern solution.
