 * Deprecated since 8.3.0

 * Originally we created the mobile theme feature as a fall-back
 * when the regular theme did not include a mobile view.
 * Most themes include a mobile view by default now, so the feature is no longer necessary.
 *
 * Visit this page for some alternatives:
 * https://jetpack.com/support/mobile-theme/
 *
 * If you MUST continue to use this module, you can use this standalone plugin as a temporary solution:
 * https://github.com/Automattic/minileven
 * However, we do not recommend it.
