It took 5 days for me to receive the SA email after eCAS changed to "decision made." I think you're totally within the normal timeframe still.Status on eCas says "decision made" for me but i still haven't received an email for SA. Meanwhilw my wife (PA) got medical request same day the status on ecas changed to decision made (feb 22). Should i be concerned yet that i haven't received an email with SA. Could "decision made" be negative in my case?
As @ryester says, the fact that they're proceeding with the medical request at all reads positive as well.
