Knowledge Base Issue and Resolution #16982 states "To find the LinkedIn ID for a contact, view the contact’s profile in LinkedIn and copy the number shown in the browser address bar after “id=”." I've followed these instructions for years with success. Even though the url format has changed over time, you can still decipher the LinkedIn ID from the url.
Recently I've noticed some LinkedIn ID's are numeric and some are alpha-numeric. The numeric LinkedIn ID's work with the GM+View, the alphanumeric LinkedIn ID's do not. Has anyone found a solution for the alphanumeric LinkedIn ID's?
