Apps uninstalling themselves

[Android Central Question]

I have installed Microsoft Word three times in recent days and even though it works fine, when I try to use it again, say next day, I find it has disappeared from the app store. I have a Moto E3 with Android 6.0

Welcome to Android Central! It disappears from the app store or the App Drawer? Are you installing it from the Play Store, or from somewhere else?
