After connecting your LinkedIn Ads account to HubSpot, your existing LinkedIn Lead Gen ads will automatically appear on your HubSpot ads dashboard. If you encounter any issues when syncing leads from your Lead Gen ads, follow the instructions below.
Lead syncing requirements
To sync leads from LinkedIn Lead Gen Forms, the user who connects the LinkedIn Ads account must be a Page Admin or a Lead Gen Forms Manager for the associated LinkedIn Business Page. To view the permissions of each user who has access to the page in your LinkedIn Ads account:- Navigate to the Campaign Manager.
- Select the business page associated with your LinkedIn Ads account.
- In the upper right, click the Admin tools dropdown menu and select Page admins.
Troubleshoot lead syncing
If you're unable to enable your LinkedIn Ads account for lead syncing, it may be a permissions issue. Ensure that you have the required page-level permissions.
If you've enabled your LinkedIn Ads account but leads aren't syncing as expected, try the troubleshooting steps below.
Check your report filters
Depending on which attribution report you've selected in the ads dashboard, some synced leads may not display.
For example, the First form submission attribution report will only show the contacts who were created as a result of filling out a lead form. If a contact existed in your account before converting on a lead form, they would not display with First form submission selected. 
If some leads appear to be missing, navigate to your contacts and search for them by email address. Synced leads will have an ad event and lead ad form submission event on their contact record timeline, which you can use for list and workflow segmentation.
Marketing Hub Professional and Enterprise customers can use the All form submissions attribution report to see all leads that have synced from their lead ads.
