Hi everyone - I'm a R2 applicant as well. Here's a brief timeline of my application process:
May 3rd: Submitted the online written component of application
May 18th: Completed online GMAT exam
May 21st: Completed video essays
A bit of background: I wrote the GMAT 4 years ago and scored a 650 (Q47, V34). I knew this wasn't competitive enough and so I decided to take the GMAT again. I prepped for two months under the assumption that an in-person GMAT exam would still be administered in my city (Toronto, CA). Unfortunately, testing centres were shut down and like most others, I decided to write the online version, knowing fully well the whiteboard would be a huge detriment to my Q score. Ultimately, the exam experience was a pathetic and frustrating one - scored a Q36, V40 (620). I shared this with Estelle and she mentioned that the AdCom is fully aware of student's frustrations with the online GMAT and takes this into account when reviewing test scores.
Long and short of it? If you have an opportunity to take an in-person GMAT before July 20, I suggest you do it. Personally, I did not have a great experience with the online exam, particularly in Quant. I'm not a Quant whiz by any stretch, but I'd never scored below a Q46 in any mock. Imagine my shock when I saw a 36. The whiteboard is a terrible piece of technology, particularly to solve these kinds of quantitative problems efficiently and effectively.
Not sure whether Insead will combine the highest of my Q47 (first GMAT) and V40 (second GMAT) scores to get a more accurate representation of my aptitude, albeit across two different tests.

Looks like we will be competing for a spot at INSEAD

I am from Toronto as well. Personally, I have not taken the GMAT yet, so having a score is definitely better than not having one. I think for your case, 620 is on the low end, especially with Q36. Not sure how they will judge things this year, but normally, they will not take Quant from one test and Verbal from another one. Imagine if all student only focuses on Quant during their first try and have a low Verbal and high Verbal on their second test with low Quant. this would be a bit weird.
That being said, by talking to alumni, I feel INSEAD is one of the schools that truly focus on things outside of the GMAT. What did you study for your UG? What's your GPA? Do you have EC? How strong are your leadership skills? Do you have true international experiences? How about your recommendation letters?
TL;DR: I think you should not worry too much about GMAT, it's just a small piece of the puzzle

A fellow Toronto-nian! Great to hear from you. Yes - you do make a valid point. Under normal circumstances, assessing two separate tests scores and combining them to form a "super" score is certainly not par for the course. Nonetheless, in light of Covid, I am hopeful that the extenuating circumstances we now find ourselves in lead to a little more sympathy and understanding from the AdCom.
As for my profile, I've lived in 4 countries (Canada, US, UAE, Oman). Studied Computer Engineering / Management Science at the University of Waterloo. UG GPA not great (3.0). 6 years in tech consulting & digital strategy at Accenture and IBM. Currently working as a Program Manager at the Bank of Montreal and startup consultant/advisor with a local incubator. A reasonable amount of volunteer and leadership experience both in and out of the workplace in the education / social impact space.
GMAT is just one part of the puzzle undoubtedly; I'm hopeful other parts of my application and career narrative are compelling enough to warrant a spot. Have you already submitted for R2? What are your GMAT plans?
