Windows 10: Are all windows store apps updates are checked before available to windows store?

I read that when a developer an app to windows store it is being checked and scan. I found this here . I do some doubt so I want to ask if the Microsoft Team checks the app updates before making it available? To expound. A rouge dev can submit a proper and honest app to get the approval from Microsoft Store Team. Once approved, the developer can now make a request without our knowledge, obviously and update the app now with the malware or rouge code. Is that possible? Or does the MS team checks the updates before making it available for download? I remember there was this app in android that

Microsoft is purging a lot of low quality apps from the Windows Store

"Microsoft is sending emails to some Windows Store developers informing them that their apps have been removed from the Store for violating its quality standards."

"Neowin reports that app developers have been receiving these emails over the past couple of days:

In its latest review of the Store, Microsoft is evaluating if the published apps are good enough to be listed in the Windows Store. This includes publicly available apps as well as private beta apps. Additionally, Microsoft is also asking developers to delete any promotional campaigns for their apps to prevent advertising charges. Similarly, app name reservations are also being nullified; which means that if your app is unpublished, there's no guarantee that you'll be able to republish it under the same name.

Officially, the policies for the Microsoft Store says that apps must have "distinct and informative metadata" and "provide a valuable and quality user experience". There are also some specific standards that must be in the apps, including having a name that is not similar to another app or device, along with offering a description that is accurate about its features and functions.

There have certainly been many Windows Store users who have complained over the years about the large number of apps published that are clones of other apps or ones that are simply poorly made. Hopefully, this new move by Microsoft will help to curb these issues, at least for now."

Windows Store Update App Number Incorrect

Good suggestions, but I already tried the Store troubleshooting process on the desktop and SP4. It is not available on mobile.
I do not synch between devices.
Even if there were an issue with a specific app (which I don't think is the case) it is the Store that reporting that one app has an update available but then does not show it the available download list.
