Description of what you need help with:

Steps to reproduce the behavior:

  1. I don’t know what is the problem with" prpperties are identical,change a property to animate.",sometimes if I group it or change a title I can animate, but sometimes I found it couldn’t be animated.

Screenshots/Sketch File/Principle file: (if applicable)

Principle creates auto-transitions and animates the layers with the same name when changing from one screen to another, if all the properties of an object are the same, then Principle won’t do any transition.

In order to Principle to animate things there must be a property change.
