Hi,

can anyone please confirm whether Guest User Security settings in Summer'20 will impact the communities without "Public Access" enabled? I was confused that the release note says that "These changes affect all customer organizations with Salesforce public sites built on site.com, force.com, or communities." But I am not sure what is a public sites built on site.com, force.com, or communities.

And another question is whether all communities allow guest user to access? 

Any comments and suggestions on my questions is highly appreciated.

Best regards,

Faxue Zhang
