If your CRM Administrator changes, be sure to have your new CRM admin invited as a user in Leadfeeder. Once they have accepted the invitation and logged in they can reconnect the CRM and get the admin updated.
STEP 1: Navigate to your CRM settings in Leadfeeder under Settings > Account > Integrations. Select your CRM (it should be listed) to go to the CRM settings page.
On that page click Reconnect.
STEP 2: On the connection details page you will see the current settings. Click Reconnect. Follow the prompts and logins and your reconnection and admin switch should complete!
