Source: Youtube web app gains PWA install prompt – may be hinting at offline support
The Youtube web app is now showing the PWA install prompt in the Chrome Omnibox for some. It’s important to note that some users have stated that they’ve seen this for a while now, but a mass rollout is significant versus a few people testing it in stages.
We’re seeing Google aggressively push the idea of turning many of its services into actual PWAs as they begin placing them in the Google Play Store in place of traditional apps.
More importantly, Google recently began enforcing a policy that would require developers to provide some form of offline functionality in order to make this PWA install prompt appear at the top of the Chrome browser.
