I tried contacting support. Last thing they said was to wait for update and not to delete but update the game and it should solve problem. I did just that when my game was using 3.8GB of storage and it's now at 4GB. Still increasing and I sent another inquiry about the issue but haven't heard from them.
Is there anyone else who has this game taking up so much space on their phone? If you have a solution to reduce to at least 1.5GB or less please let me know. This game is awesome and I put money into it but it might end here if this isn't addressed and fixed.
Thanks for your time and feedback in advance!
