Android Releases in the Google Play Store: Where is the Opt-in URL?
It's just a matter of time
- Rolling out merely gets you to the Pending publication stage
- After some time (say 45 minutes) you will reach the Published stage and the Opt-in URL
For many developers, it's just a matter of time. Rolling out merely gets you to the Pending publication stage. After some time you reach the Published stage and the URL will appear.
However, for your app, it looks like this app in unpublished. You can't opt-in to unpublished apps, so the opt-in link isn't shown.
For questions like this the Developer support team are usually really good, and we do have bugs sometimes, so it is always worth asking them.
