Miscellaneous Information:

I see there’s a Github issue label workaround/allow-all-cookies which could be added to this issue. I wonder if there’s a feature request in here somewhere that would have a teeny popup that suggests to end users, “this website might need all cookies enabled” or something. We certainly can’t compile a list for every website, but might possibly compile a list of major sites where this applies.

The main issue here, weebly is calling cookies from editmysite.com, which is why its weebly having issues. Currently we don’t have a whitelist to allow all cookies just yet, so just allow all cookies for the time being.

Hey @mikedotexe is this still an issue?
