What's new
A refusal you asked to be remembered now holds even while automatic approval is switched on, and a permission you set to ask now asks instead of being approved for you. Both were being overridden by the automatic setting before. An app whose access window has run out has to be approved again rather than quietly falling back to your default setting, and its permission to sign in the background is withdrawn. A refusal is kept for as long as you set it.
