Why is it important to check an app's permissions before use?

If you don't pay attention to the permissions, you may give apps access to more information than you'd like. Android and iOS both provide tools (in the settings) that allow you to have some control over whether an app can get or use specific types of data.

How do I give access to model driven app?

When you share a model-driven app, you can share it with all members of one or more security roles or a user or team. Sign in to the Power Apps, on the left navigation pane select Apps, next to the app you want to share select …, and then select Share.

How do you use Power Apps forms?

Power Apps makes building data entry forms surprisingly simple – just insert a new form onto the screen, watch all of the fields in your data source magically appear in the form, then add a 'submit' button and you're done.
