Compatibility between 2016.1.5999 and 2018.1.4


#1

Do you know differences in 2016.1.5999 and 2018.1.4?
When I made some click activities with 2016.1.5999 and worked with 2018.1.4 ,
Some click activities didn’t move and showed errores below.
I took capture with 2018.1.4 again using Indicate on Screen,and they workded.

But wordings in Selectors were the same, Do you know the phenomenon?
