Ha! No! My ECAS is alive! ;D
I have a double name, meaning two last names connected by a hyphen. I actually had to type in the double name with a space and then it worked! So if your last name is e.g. "Smith-Miller" you will have to type in "Smith Miller".
My ECAS now states the following:
1. We received your application for permanent residence on December 8, 2014.
2. Medical results have been received.
Shouldn't it usually state something about the RFPR fee as well? In my AOR they acknowledged my payment of $1040 but they are not mentioning it in my ECAS...
