Achievement completion banner

Hi, my achievement completion banner is not showing, but in console it shows the achievement was completed. I have .showCompletionBanner set to true. Is this a sandbox issue? And if it is a sandbox issue does this mean my users won't be affected when it goes live?

Hello, you need sandbox account and development build for popup showing up.

@taptouch Did you solve the problem? I have the same behaviour and I don't have a clue. It's all setup, the user is logged in and the achievement is shown as completed after setting the "percentCompleted" and the progress is reported. But no banner is shown, despite "achievement.showsCompletionBanner = true" is set.
