⚠️ Please note that this feature is only enabled in WordPress. This feature is disabled for Jetpack. ⚠️

WordPress-iOS/WordPress/Classes/ViewRelated/Me/App Settings/About/AboutViewController.swift

Lines 280 to 283 in a56e6a6

	/// Convenience property to determine whether the recomend app section should be displayed or not.
	private var isRecommendAppSectionEnabled: Bool {
	return FeatureFlag.recommendAppToOthers.enabled && !AppConfiguration.isJetpack
	}

WordPress-iOS/WordPress/Classes/ViewRelated/Me/Me Main/MeViewController.swift

Lines 413 to 416 in a56e6a6

	/// Convenience property to determine whether the recomend app row should be displayed or not.

To test:

• Go to Me screen. Verify that the share button is visible, accessible, and works as expected.
• Go to Me > App Settings > About screen. Verify that the share button is visible, accessible, and works as expected.
• Repeat the above 👆 with a self-hosted site. Verify that the share button works without a WordPress.com account.
