Yes I signed by my name and initial and submitted after uploading and on the document section of portal it says replacement provided. But in the steps it stocked on your action is required!Are you sure you have submitted and electronically signed completely? A friend of mine just uploaded and did not know that he needed to sign and submit completely so the EXACT thing happened to him. Please check if you have done these crucial steps.
Know that if you did not submit correctly and the deadline has passed they will remove the submit button and you need to contact them urgently via webform and also call them.
I also sent an webform 2 weeks ago with same documents and mentioned all this but no respond yet.
