To prevent Android users from getting confused, Google is asking app developers to do one thing
“Developers with a video in their store listing must disable ads by November 1, 2019, to keep the video eligible to be shown on Google Play. This is because, beginning September 2019, Google Play will start auto-playing store listing videos to help more users discover your content at a glance. If those videos are monetized (that is, enabled for monetization on YouTube or containing copyrighted content with monetization claims), they may show ads, which can be confusing for users.”-Google
YouTube recently started auto-playing videos found in the subscription tab but does include a toggle switch allowing users to disable the feature. And speaking of YouTube, the videos that automatically play in the Google Play Store will be muted just like they are on Google’s video streaming site. Still, this is a good way for developers to attract attention to their Play Store listing; a video clip surely catches the attention of Play Store browsers more than a still photo does.
