An issue has been reported in Reckon APS Tax 2019.5.0 and Reckon APS Tax Manager & Elite Forms 2019.5.0 where the Auskey fails to pass the Test after been updated by the ATO.
If your Auskey has been recently cancelled or updated by the ATO, you will notice that the updated Auskey has more than one entry in it with the same details. When setting up the Auskey profile, upon clicking on the Test Connection you might receive the following Error:
SBR Auskey Configuration
Test has failed: Engine error: Exception [NullReferenceException], Message = Object reference not set to an instance of an object.
This will be resolved in Reckon APS Tax 2019.6.0, in the interim please contact support for a work around.
