Guest are seen as private user, even inside the same team or same project


Since this morning suddenly it is happening on my Asana account that all the team and project members who even have full access in teams as they can edit it as well and the projects are public as well but still members are seeing each other as private users.
Also, they are not able to see each other while tagging each other in comments. This issue started happening this morning as till yesterday all was OK. Please resolve my issue and tell me what to do? I am using Asana on Google Chrome Version 81.0.4044.129 (Official Build) (64-bit)
For your reference i am attaching screenshot of the issue
