GLD Remote

Is there a legacy version of the GLD Remote App that is compatible with GLD Firmware v1.51?

under Software are older editor versions available

We just updated our board to the 1.61 version and updated the app on the iPad but when you try to connect the iPad to the board we get a message that says connection failed mixer connection error anybody have any ideas thanks
