There is a problem that I cannot add a new user and share the form with the team

@khlood, FYR:

Username is not found in Sharing

Kindly please be informed that sharing a project with other users is only possible if both the user account is within the same server i.e. it should be either in the OCHA server or it should be in the HHI server. Sharing a project across a server is not possible i.e. a user wishes to share a project from OCHA server to HHI server or vice versa.

For details, this support article Sharing Your Project and Managing Permissions should also be able to explain more.
