Why doesn’t the left-hand menu show all the companies a business partner user is linked to?

This feature is available on all Deel Local Payroll powered by payspace editions
The left-hand menu only shows companies within the same company group.
To access companies outside of this group, the business partner will need to use the Company Search function.
For example: Support Ops - Premier is not part of the same group.
Support Ops - Premier can be accessed from the Company Search.
