I published my app update yesterday and users can manually update it on Google Play, but it should be installed automatically.
Does this have anything to do with my certificate? I receive a warning that it does not have a timestamp.

When apps are updated on Google Play, Google reviews the app and then makes the new version available for download if you go to the app in the store (this is in their policy) pretty quickly.
Based on experience, once the new version is "available" for download that does not mean that Google Play automatically and immediately updates the installed user base. I can speculate on why this is happens (bandwidth distribution, polling schemes, allowing developers time to monitor the update feedback, etc.).
But I am certain that not all users get the update immediately even when "automatic updates" are turned on. It takes some time for the update to propagate, maybe a couple of days. I have users that don't seem to get updates for several days even with "automatic update" turned on.
(Also, your question should read something like, "Android App not automatically updated on devices")
