I did not think this was possible until i noticed on the Customer record on the mobile app you can open the Appointment History (Appointment Summary) screen.
On the Customer record there is an Action called Equipment Summary which opens the Equipment Summary GI.
When i try and add this to the mobile app the action is there but when i click it i get a redirect fail

I have tried changing behaviour to void and also changed recordAction to ViewEquipmentSummaryInquiry but keep getting same error. I also tried redirectToScreen = “FS400200”
