This "feature" has been moved to defaults in Chrome 80. If you're experiencing issues, you can do the following:
1. Go into the "Chrome Flags" chrome://flags
2. Search for same
3. Disable "Enable removing SameSite=None cookies" and "Cookies without SameSite must be secure" flags
This should get you back up and running until a more complete fix can be suggested.
