This may really be a bug report rather than a question, please refer me to the correct place if this is not it.
The Chrome developer console issued the following warning:
A cookie associated with a cross-site resource at http://mixpanel.com/ was set without the `SameSite` attribute. A future release of Chrome will only deliver cookies with cross-site requests if they are set with `SameSite=None` and `Secure`. You can review cookies in developer tools under Application>Storage>Cookies and see more details at https://www.chromestatus.com/feature/5088147346030592 and https://www.chromestatus.com/feature/5633521622188032
I was looking into how to add a "SameSite=None" attribute to the MixPanel cookie, but quickly realized that maybe this shouldn't be my problem.
Should I adjust the cookie to have the new attribute myself, or is that MixPanel's problem?
Specifics: Windows 10, Chrome version 77.0.3865.90, my website if it's relevant.
