Help users reverse their primary decision easily

Some users are very reluctant to give permissions unless absolutely necessary. Because of this, they may initially deny permissions that they’ll later decide to grant. In short, it takes time to build their trust.

When they finally do decide they need to grant permissions to use a particular function, make it easy for them to reverse their decision. Give them a polite explanation of why they can’t use the particular feature, and then give them a direct link to their device’s settings in order to grant the permissions.
