Hi,
I have also got the funding and received the health insurance documents a few days ago. Like in your case, I haven not received any other communication regarding the Declaration of Acceptance. But reading the scholarship booklet they sent with the letter of award, I think the health insurance documents are only sent after one submits the consent for processing medical data and accepts the scholarship. There is nothing else written about the Declaration of Acceptance. So I think it is fine.
Just one question - did you put a tick mark or something to each point in the Declaration of Acceptance before you uploaded it? Asking since the booklet says no changes/additions are to be made to the Declaration and so I uploaded the document as it is, but a little worried if it is okay.
Best,
