Answer 1

One of the big iOS/Android projects I work on uses GTM variables for remote configuration.

For example, our menu items change based on whether it is Winter. So, we flip a boolean on GTM, and voila, within 24 hours, all our apps have the correct menu items.

We are planning to migrate this functionality to Firebase database, however, which has the benefit of instant updates.
