Play Store is not loading LGG4

[AC Question]

After the Marshmallow 6.0 , i have been getting notifications stating my google play services is "not updated" a few months ago. The notifications have stopped and now my google play store will not load. When i open the app it just takes me to a white screen. I have tried force stopping and clearing the cache of the play store, but it only shows me a loading wheel that just continuously spins for hours. I have tried downloading apps through a browser, but it just sends me a notification days later saying the app is unable to download. Thanks if you can help.
