Notes: Jira ticket

Original report: https://forum.mattermost.org/t/ios-app-ignores-safe-area-in-landscape/6540

The iOS app implements the SafeAreaView for the iPhone X family but the screen on landscape mode does not respect the horizontal margins, thus some content is not visible.

We need to include the horizontal margins in Landscape mode so the content does not get cutoff.

Hey @albertoestarrona! How is your work coming along? Please let me know if you have any questions.

Sorry for the delay and no news over the last days @migbot, but just started today with this one. This week was really complicated. I'll give you an update (hopefully it'd be ready) over the weekend.
