Latest open paas is not listing the users in chat and email

Hi,
I took the latest code (today) and not able to pick the users in TO box in email and Chat Direct messages. It use to show all the users. Now it is not listing. It used to work in previous versions.
Are there any additional settings needs to be done? Am I missing any steps here?

Thanks


That chat is disabled too. But it is enabled in platform and domain level. This user is able to login as well.

This is in communities :
