Simultaneous PSM sessions only with Automatic login.
The option "Maximum Simultaneous Sessions" is grayed out on PSM details Tab, why?
If you would like an Account to be available for multiple requests at a time, you must set the "Max Simultaneous Sessions" to a value greater than 1.
If the "Maximum Simultaneous Sessions" option is grayed out or disabled for an account, this is because the ability to have multiple simultaneous requests on the same account is only available if you have the Proxy Type set to Automatic Login. Proxy types that use Interactive Login options can only have 1 request at a time.
