Hi!Same thing happened to me.
My eCAS, on sponsored side (Permanent Residence Application Status) changed to "In process" from "Application Received" and on sponsor's side (Sponsorship Application Status) changed from "In process" to Application received". No messages when I click. Nothing has been changed on MyCIC account either.
I hope is a good sign
I had the same thing.
I checked my ECAS on June 4th-<Medical results have been received> -IN PROCESS BOTH SIDES
Then just today,June 6th-In process changed to <APPLICATION RECEIVED>
What does that mean?
