If you are an Android user, then you always download all the latest apps, games and also update them through Google Play Store. Since last two years, the app has got tremendous improvements in every single aspect be it in the UI or UX. Recently Google is testing another different UI for the Google Play App itself. Now you can also pause your downloading while using Mobile data thus giving an option to be on the safe side.
The app itself gets updated a lot with so many bug fixes and improvements. A new update is already there which may include bugs fixes and maybe the new UI system. Google doesn’t reveal any changelog for this app. Thus we have to guess it but anyway every update adds something new so updating the app gives more stability.
Anyway, you can easily download the latest Google Play Store app from APKMirror if you are not able to update it from the app itself.
