Error Cancelling Domain Transfer

I’ve been moving several domains to Cloudflare but a few of the transfer confirmation emails from my previous registrar did not make it through.

I’m trying to reinitiate the transfer by canceling the current transfers so I may restart them.

When I attempt to do so, nothing occurs. I receive the following error:
{"success":false,"errors":[{"code":9300,"message":"User session has expired. Please log in again"}],"messages":[],"result":null}

I’m logged in. I tried logging out and then back in to try again but still receive the error.
