Issue with chrome 80 and SameSite cookie changes

Hi there

I run my own notebook hosting platform

a few weeks ago some users have complained about getting a 403 Forbidden when loading their notebook; I have started to document my findings on this matter https://github.com/parmentelat/nbhosting/issues/111

it appears the issue has to see with a recent change in chrome, being currently rolled out, and outlined in this post

I was wondering if anybody had been exposed to something similar recently
