I didn't call but I received my GCMS note last night. It shows as of 03/18, my criminality is passed; for type "Biometric - FCC Detail" info sharing, my status is "Complete - Assessed"; for type "Biometric - FCC", my status is "Complete - Not Reviewed". So, my info sharing remains "In Progress". My security is blank in the notes, which I don't know what it means.
Hope this information help.
The GCMS generated on Mar 18, so compared to your timeline, it was in progress at that moment but must be completed on Mar 20, hence the change in status for background check. I think everything should be done at this point, they just put us in a queue to generate COPR and send out portal emails. If not that I don't understand what else they need to do, and the tracker would be useless when it shows all completed, but there are still things to work on.
