If new updates are available in the Google Play Store, this does not mean that a new update has actually been published for the app. In some cases, the user will be asked to download updates that have already been installed.
According to 9to5google, this should be a new bug. The error should only have existed for a few days. Since Sunday, many users have seen a long queue with pending updates. The apps listed there were largely developed by Google itself. In addition to services such as Google Docs and YouTube TV, Android applications from third parties should also be found on the list.
The updates have already been installed
However, developers are likely to provide feature updates for their apps over the weekend. Further investigation then revealed that the pending updates are updates that were installed earlier. While some updates are only a few days old, other updates have been available for months. If the updates are downloaded a second time, the apps may reappear in the list of pending updates. So far, Google has not officially commented on the problem.
Although it is an annoying bug, most smartphone owners should not be harmed. The reinstallation of an update has disadvantages for only a few users. Since each time an app is downloaded, additional internet traffic is generated, users with a volume tariff should forego automatic updates and only allow downloading via WiFi networks.
