However, it accrues AS miles like a premium Y ticket because that's what it is and always was. Y, E, and A were Economy Comfort and were never J cabin fares. Occasionally, EC+ passengers would get a Saga seat on a space-available basis, but it didn't include the Saga food or other amenities. Interestingly, E is now "discount" Saga (cf. C, D, J "true" Saga fares) and Y and A are now just high-fare Economy (won't even get a Saga seat once the EC+ ticketing phaseout is complete).

I'm assuming you've confirmed that your seats are indeed in the J cabin, in which case you've gotten it done inside the window.
