To show a component that shows LinkedIn data only to sales users when they are on their mobile phones, the administrator should filter the component visibility with two conditions:
User > Profile > name = sales User, which checks if the user's profile name is "sales User" Form Factor = phone, which checks if the user's device is a phone Filtering with view or role will not achieve the desired result.

To route new leads to the correct sales person based on the lead address, the administrator should use lead assignment rules that specify criteria based on lead fields such as City, State/Province, or Country, and assign leads that match those criteria to queues or users. Lead assignment rules can be triggered automatically when leads are created or manually by users. Creating a formula field, assigning with an escalation rule, or configuring a validation rule will not route leads to sales people.

One of the possible reasons why an administrator is unable to add a new user in Salesforce is that the username is already in use by another user in any Salesforce org. Usernames must be globally unique across all Salesforce orgs, so the administrator needs to choose a different username for the new user.

Prebuilt email templates are email templates that have been created and provided by Salesforce for common use cases such as sending welcome messages, confirmation emails, etc. They can be used by Cloud Kicks to have consistency when communicating with customers on cases via email channel with categories to help search for the proper message. Prebuilt email templates can be accessed from the email action in the case feed or from the email composer in Lightning Experience. They can also be filtered by category to find the most relevant template for each case. Prebuilt quick texts, prebuilt flow templates, and prebuilt auto-responses are not solutions for having consistency when communicating with customers on cases via email channel; they are used for different purposes such as inserting common phrases, creating guided processes, or sending automated replies.
