Google Play Store wont load , stuck at white loading screen

[AC Question]

I gave my cousin my Lenovo IdeaTab A-3000. But when he tries to open up the play store, it stuck at the loading screen.

Go to system settings, then enable application installation from unknown sources, followed by downloading the Google Play Store apk (can't link this, but just google it) and re-installing (or updating) Google Play Store

This fixed the issue for my old Galaxy S2. Best regards
