Take note that multi-user support is only available in the beta version of Instagram for Android. This means that if you are running the full and latest version of the public release of Instagram, don’t expect to find this feature just yet. However it is possible that the feature could be ready for primetime soon.
In any case like we said, the appearance on both Android and iOS has led us to believe that Instagram might be getting pretty serious with this feature, as opposed to it being an experiment. It’s really anyone’s guess as to when it will be released, but for social media managers and users who have multiple Instagram accounts, this might just be the feature you’ve been waiting for.
