You may have an unauthorized version of the game installed on your phone. Such as, downloading a mirror of the app off of a website. Only authorized versions of the game from the Google Play Store will receive updates.
That being said, be careful with installing any apps off of websites because these apps are not checked for viruses, which may result in you losing Access to your account completely. Hope this post helped, happy Scaping.
