If you've heard about a new feature in Blink but you don't seem to have access to it, first check that you're using the latest version of your client.
Just refresh your web browser to load the latest version of the webapp
Simply close and re-open the desktop app to load the latest version
NB Clicking "check for updates" will only check for updates to the framework that the desktop app lives in. It won't necessarily reload the latest version of Blink.
iOS and Android:
Head to the App or Play store to check for updates to the apps.
If you still can't see the feature you're looking for, it may be that it is a beta or pre-release function (want to join the beta programme for your platform?). If you're still not sure, feel free to raise a support case and we can help you out!
