Chromium 80 will be changing its behavior regarding the SameSite attribute in cookies. There are a number of Glitch-controlled cookies that do not have that attribute, and it is resulting in warnings being printed to the Chrome console:
A cookie associated with a cross-site resource at http://glitch.com/ was set without the
SameSiteattribute. A future release of Chrome will only deliver cookies with cross-site requests if they are set withSameSite=NoneandSecure. You can review cookies in developer tools under Application>Storage>Cookies and see more details at Chrome Platform Status and Chrome Platform Status.
