Field Service Org Setup

Create a permission set with the Access Lightning Web Components in Field Service Mobile permission, and assign this permission set to users who develop for or use Lightning web components in the mobile app.

This step is required for Field Service orgs. If you’re using LWC Offline in the Salesforce mobile app, skip to the next step.

Note

Lightning web components for LWC Offline-enabled mobile apps is an opt-in feature. To enable it for your org, you must create and assign a permission set for your mobile users that includes enabling the Access Lightning Web Components in Field Service Mobile permission. This permission set is required to access and run LWCs within the Field Service mobile app. (While not technically required to develop LWCs, you’ll have a hard time developing components when you can’t run them.)

You can use this one permission set for any number of Lightning web components and mobile users.
