What Type of Bug are you experiencing?

Devices

Summary

Using input trigger with standard action input type doesnt work for mobile devices. For example when using fire input and subscribing to any event or calling any function on this device, it doesnt give any result, while it works fine on pc or console.

Steps to Reproduce

  1. Place input trigger device on the island
  2. Set input type to standard action
  3. Subscribe to any event or call any function on this device in verse

Expected Result

When f.e. pressing fire button it would call a function subscribed to PressedEvent in verse, or when calling IsHeld it would fail if player is not holding the button and succeed when player is.
The result should be exactly the same as it is on PC or console

Observed Result

None of the functions or events give any result

Platform(s)

Mobile

Additional Notes

It seems that it works for creative input action type, but it doesnt for standard action
