New clients as of the middle of January 2018 have the New Spending Interface turned on automatically. If you'd like more information on this feature, please contact support@fundriver.com.
The first indication that you have the New Spending Interface turned on is the new ASSIGN SECONDARY RULES tab on the SPENDING RULES page.
Additionally, the New Spending Interface has a PARAMETERS WITHDRAWAL and UNDERWATER section under the SPENDING RULES tab.
The Old Spending Interface does not have the ASSIGN SECONDARY RULES tab.
The Old Spending Interface only has a single PARAMETERS section under the SPENDING RULES tab.
