It would be far easier to just tag them and have them address it directly, no? I have no idea about the history behind either of these - so let's let
@505 Games Support and
@505Games-Mobile weigh in.
As far as I am aware, this is a third party app that has NO relationship to 505 or Re-Logic or anyone related to the development of Terraria. That really would be more of a question for the app developer....unless you are asking them why they allow it to exist in the first place? In which case, they would need to answer.
Sorry, this is a lot of stuff they will need to address, so I've tagged them and let's see.
