Now latest status is changed back to Medical passed.
Below are the changes to my profile in latest status from yesterday:
Final Approved -> Medical Passed -> Final Approved -> Background passed -> Final approved -> Medical passed
I dont think these are ghost updates instead look like a glitch or bug after system maintenance. Ghost updates are those where your application status is changed to "Application/Profile updated" and once you go inside your profile application status is changed back to original.
I agree. I am finding it difficult to be positive now about these random cyclic updates that have been happening on my profile. Since today morning, I have logged in thrice and every time the status changed to either medical passed or Final Approved. This looks like a glitch unfortunately for most of us. IRCC still appears to be super selective about who they want to issue those ALs to so this continues to be an excruciating wait.
