I have an issue with project review timelines for Connect Mentorship Nanodegree

I have submitted my first submission and the feedback was not very helpful (which took a lot of time to get back), following which I submitted the second submission 2 days ago. Udacity urges me to complete the projects by 31st May (today) while the turnaround is really massive. It's been 2 days since submission but no feedback. Can you extend the deadline, if you are can't provide feedback faster ?
