Really niche question, but wondering if anyone has used the edit feature in the "document upload" tab on an application (specifically one that uses AMP). I submitted an update letter to a school last week and just realized that it has a typo. When I hit the "edit" button next to my document, it looks like I can delete and add a new file. My question is, if I do that, will the "Uploaded" date change with it? It is important to me that the date doesn't change, so I wanted to see if anyone has experience with this before I do it.
 
I think the uploaded date changes, but not sure. The schools I've used with AMP didn't offer retracting documents.
