Call of duty (Garena) (Private Game) 23/7/27

Hi, my name is K i just wanted to say that, is this game is different from a garena app? Like why does this game is not a garena? Because my current game was a (GARENA) and it is different from this game i play right now, or maybe that Call of duty Garena I currently play while i am in the PH is a private game, its just sad that i cannot play my current game that i am in japan right now : i really miss my current (GARENA) account or maybe there's many call of duty apps like this, its just that what I currently played was a (GARENA) and right now its not a garena its a normal Call of duty ever since i have a new phone that i buy from japan, maybe it's because of my location? Why does it have to do with it? But i can switch to my apple id from PH and i installed Call of duty Garena and after its installed it is said that "this app has not yet been released in your area" what does that mean? Does it mean, its because my country is located in japan and because i buy my phone in japan not in Philippines? I really want my account back but this game is not a garena and i need to creat a new account, and i cant join with my friends in Philippines like how we used to play while i was still in the PH....😩
