I am having the same issue. I have the Moto e5 play and I’m in the United States (with a US Play Store account) but for some reason it says that it is not available in my country. (Tried to upload a screenshot but I don’t have permissions to upload images). I really want to play this game. It shouldn’t be a compatibility issue from what I know because the game requires Android 5.0 or later and I have 8.0 so that shouldn’t be the problem. Also I would expect it to say that it’s not compatible with your device, not that it is not available for your country.
Same i have a moto e 5 cruise and also says its not available in my country. I don’t get it why is it not on the compatible or non compatible devices list.
You’re not alone bro. I have the exact device and it’s doing the same crap to me. I have no clue what to do.
