Working for a client... I gave my NS access to another employee of my company (edited the employee record and just updated the email to their email) But when they try to give me access back (doing the same) they are getting this error message: This user has different email addresses to login into the system and receive notifications. Please update this record with the email address, you want to be used as a login name and notifications. We also talked to the client about getting a second license so we don't have to keep swapping access--- I'm almost wondering if they created an employee record for me and now NS thinks it's a duplicate? Has anyone seen that error message before?

this is the standard behavior for the miss match of the employee record's base email address and access email address. Note an user can change his/her login email from the setting menu on their NS homepage.
