I am level 47 and have it and I can see it on all my neighbours' farms. I checked on a level 9 farm with no expansions and could see it.
I think if you have it you can see it on all other farms and if you don't you can't see it on any.
I am in the UK btw and I noticed that mymummy789 is too which is why I wondered if it depended on which app store you use.
