These are two different tools with different info in it. I even cannot find criteria to compareQuestion to everyone, especially to those whose checking GCKey and eCAS on a regular basis
Is there anything you can see on eCAS but can't see in emails from IRCC / in GCKey?
Just going forward: I know the difference between eCAS and GCKey. I know the purpose of both and how they look like. I'm just curious: if you linked an application to an account, what is the purpose of checking eCAS? Say, SA on eCAS is just "decision made", but it can be negative, right? An email is providing much more info. Same for all other stages. Maybe someone can point out a case when eCAS is particularly helpful? Thanks everyone.
A bit of patience and you will experience both soon
