[Android Central Question]

Has anyone else been having problems with this?It used to keep my data even if I uninstalled the game.Now Everytime I reinstall a app it wipes all my game data, even doing a data restore doesn't work.Btw my phone is an Android 6 so it should be able to keep my data even if I reinstall it, oh and I also tried this with three other apps so I don't think it is because of the game.

By uninstalling the app, you make the phone forget it ever existed, unless the app servers store your personal details and can resynch with your phone if you install the app again

Welcome to Android Central! It may also have to do with the app. When you uninstall an app, it's supposed to remove all associated data folders, but sometimes, the app isn't coded properly to remove data folders (or perhaps they did that intentionally). When I periodically look through my devices' data folders, I'll sometimes find the remnants of some app I uninstalled a while ago.

An app can be written so that, on installation, it looks for previous installations (folders with data for that app), or it can be written to install from scratch. That's up to the developer, it has nothing to do with the phone, the OS or anything else. The same app on Android and a Windows version may work differently (or they may be identical). Again - developer's choice. (Sometimes, in a particular environment, the developer just doesn't know how to find whether there's old data. Not every developer knows every environment completely.)
