Signed out of my LinkedIn account.

I'm completely locked out of my LinkedIn account and I don't know what else to try.

I forgot my password and what gmail address I used , so when I try to reset it, LinkedIn asks me to verify my identity through Persona. The problem is that the Persona page immediately shows an error instead of letting me verify my ID.

I've already tried: Different devices,Different browsers,Different internet connections

The same error appears every time.

The bigger problem is that LinkedIn support wants me to sign in before I can contact them, but I can't sign in because the Persona verification keeps failing. It's a complete loop.

Has anyone experienced this? Were you able to get back into your account or find another way to contact LinkedIn support?

Any advice would be appreciated.
