Just seen you reached out to our Support team about this and they identified that the error you were running into was due to the LinkedIn apps returning "Requested version 20250101 is not active" error incident: https://status.zapier.com/incidents/01KF37VDDC9VTKAJNH6KRQAY65
That’s since been resolved which should have also fixed the error you were seeing when connecting your LinkedIn account. Can you confirm whether that’s the case, or are you still running into that error when attempting to connect Zapier to your LinkedIn account? Want to make sure you’re all set! 🙂
