Thank you, Shella, for your response.
However, both companies already have separate MYOB Business payroll accounts. No need to create new ones.
We need to have to separate logins. And update second company details.
I have no idea why MYOB arranged single login years back.
Another strange thing happened this month. All over sudden both invoices came to one email, instead of going to 2 different as it was for months. However, 2FA warning came to the proper email address for the second company and to the old email that is not in use anymore. It was arranged from our side to replace that old email with the proper new email for the second company. And it was going well until this month. Some sort of glitch happened on MYOB side.
Please, assist
