There are 2 months now since may physical documents were delivered to WES.as long as you've sent them Electronically that's fine , for first method you had used before E method , it is all depends maybe to source country ,college/uni name as well , specifically in these days we are confronting pandemic .
Finally , logically and generally it takes around 35 to 50 days from delivering to final ECA , from my side , best thing is waiting if wouldn't get your ECA which has been sent through a E method , try call them , normally less than 1 week should be replied for E method
