In Mobile, when you select
Diplomacy
Messages
Start New Message,
the interface shows you a list of all countries and their last dates of activity.
On PC, when you select the same, it does not.
My concern is that this gives an intelligence advantage to mobile users, since they will have more warning that a player is active but idle, or is about to go inactive, on a particular map.
Suggestion: Either add this information to the PC interface, or remove it from the Mobile interface.
Thanks for your time.
