Connecting an ad account means signing in to the ad platform and allowing Runway to read your accounts. If that is not working, check the following.

Check your role

Only Admins and Billing Admins can connect ad accounts. If you are an Editor or Viewer, ask an Admin in your workspace to connect it.

Check your access on the ad platform

You need to sign in with a platform account that has admin access to the ad account you want to connect. If the platform shows no accounts after you sign in, your platform account may not have that level of access. Check your permissions in the platform's own settings first.

If a connection stopped working

Platforms expire access after a while, or when your password or permissions change. On the Connected accounts tab, select Reconnect next to the platform and sign in again.
