Most apps rely on user-specific data. In other words, apps can look and behave differently, depending on who's using it. As you design your app, it's important to be able to preview these different scenarios. To do this, we use Preview As.
The Preview As feature can be accessed by clicking on the Preview As icon on the left hand side of Glide. Here you'll see a list of all users that have access to your app. When you click on any of the users on that list, Glide will then display what that user would see.
If you don't have User Profiles enabled, you will still be able to preview user-specific data – but you will have to enter the user's exact email address – as opposed to searching for their name or role.
