I recently switched to modern experience, to my surprise Some properties from the for each activity are gone. I am no longer able to define the for each variable, nor the variable type, it says all properties are visible on the card but that’s not the case. is there a workaround to this?
I have had something similar happen to me. I had to roll back one of the dependencies to a previous version to fix it.
I recommend to check your UiPath Studio version and then your standard dependencies to see if going back to a previous version fixes it for you.
