When I open LP on my iPhone 12, I get the Face ID attempt prompt. But almost always LP then asks me for my password. Face ID works all the time to unlock my phone, so it's working. I assume LP asks for a password if enough time has passed since the last login, regardless if Face ID was successful. The whole idea of Face ID is so I don't have to enter my password, so why do I still have to enter it 90% of the time?
